i went to a doctor about the groin irritated skin and he prescribed bactrician zinc ointment or something
after a week of use it went away but then my scrotum started itching and it too had irritated skin that hurts whenever i sweat, so it stings
people have recommended baby powder to keep the area dry, and vaseline to moisutirize the area in case it is dry skin
my question is that, which one should i use, can i use both, and should i still use the bacitrician zinc ointment even though its past a weeks a time since my doctor told me to stop using it?I have a jock itch, does it mix with either vaseline, baby powder or bactrician zinc anti ointment cream?
You mix powder with vaseline and you are going to have a mess. You need to go back to your doc and get something stronger, like a fungicide.
Or you could wear a maxi pad. Just kidding.I have a jock itch, does it mix with either vaseline, baby powder or bactrician zinc anti ointment cream?
I used to work construction and frequently had this problem. Baby powder worked everytime. I think Vaseline actually makes the problem worse because it holds in moisture.
its from not washing yourself %26gt;_%26gt; hope it falls off
Go back to what the doc had you use. Never use vaseline on any kind of rash. It does not moisturize, but is rather like putting a coating of thick oil on the rash and it will cause severe itching. Avoid powder as well because it can irritate the area even more. Do not use any kind of moisturizer on jock itch. It will only make things worse. Use what the doc gave you. That's the best and smartest way to go.
yeah go get some lamisil jock itch creme the stuff will get rid of the itch and in a couple days it should stop burning when you sweat... i had the same problem and i tried using baby powder but honestly it burned when i put it on, and although it was dry it didn't help.
You need antifungal cream. You should be able to buy from pharmacy
don't put Vaseline on it.get a powder for jock itch,or anti fungal spray.

Zinc white -Chemical name: Zinc(II)-oxide --ZnO
Talcum powder --- is a mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2.
Washing Soda ---- Sodium carbonate --Na2CO3
Vetsin--Monosodium glutamate or MSG is the sodium salt of glutamate. When MSG is added to foods, it provides a similar flavoring function as the glutamate that occurs naturally in food. MSG is comprised of nothing more than water, sodium, and glutamate.
Pyrite :The mineral pyrite, or iron pyrite, is iron sulfide, FeS2. It has isometric crystals that usually appear as cubes.
Chlorophyll :Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from ancient Greek: chloros = green and phyllon = leaf. Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green color of chlorophyll-containing tissues like plant leaves.
Chlorophyllotion is a chlorin pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. At the center of the chlorin ring is a magnesium ion. The chlorin ring can have several different side chains, usually including a long phytol chain. There are a few different forms that occur naturally:

Powdered zinc carbonate is added to a solution of nitric acid until effervescence ceases.pH level?
Does it decrease/increase to about 7 or decreases to 3 or icnrease to 12?Powdered zinc carbonate is added to a solution of nitric acid until effervescence ceases.pH level?
A solution of HNO3 will be quite acidic, perhaps around pH 1. Adding ZnCO3 will produce CO2 gas and Zn ions.
ZnCO3(aq) + HNO3(aq) --%26gt; Zn(NO3)2(aq) + CO2(g) + H2O
When the gas production stops the H+ from the acid will have been consumed (neutralized).
In reality, there will be no Zn(NO3)2, there will be zinc ions and nitrate ions. The zinc ions will hydrolyze to a slight extent producing Zn(OH)^+ and H+. The CO2 still in solution (CO2 is soluble in water) will hydrolyze to form a weakly acidic solution:
CO2 + H2O %26lt;==%26gt; H+ + HCO3^-
From this we can infer that after the neutralization of the HNO3, the resulting solution will still be acidic with a pH closer to 6.
============= Follow up ===============
Puchhki said. ';...carbonic acid the pH will be more than 7.';
I must respectfully disagree with Puchhki. What we think of as ';carbonic acid'; is not molecules of H2CO3, but rather the equilibrium between CO2, H2O, H+ and HCO3- as I've shown above. The solution will be acidic, and therefore have a pH below 7. Carbon dioxide dissolved in water contributes to acid rain. Acid rain has a pH below 7. CO2 dissolved in water will NOT be basic as Puchhki has suggested.Powdered zinc carbonate is added to a solution of nitric acid until effervescence ceases.pH level?
effervescence cease means that nitric acid has exhausted
now the solution has carbonic acid, unreacted Zn-carbonate and ZnCl2.
because of the carbonic acid the pH will be more than 7, but not extremely high-because H2CO3 is not a strong acid

How can one separate gold from a mixture of zinc and gold? Also, how can one determine whether a white powder?
was zinc sulfide or sodium carbonate using a hydrochloric acid solution?How can one separate gold from a mixture of zinc and gold? Also, how can one determine whether a white powder?
If the white powder is sodium carbonate, when you react it with HCl, you will get carbon dioxide gas given off as one of the products of the reaction.. this gas is odorless.
If the white powder is Zinc Sulphide, when you react it with HCl, you will get sulphur dioxide gas given off as one of the products of the reaction, this gas smells like rotten eggs and is toxic.
As for the Zinc Gold mixture, you can use different methods of extraction.. both have different melting points.. you can melt the metal with the lower melting point and pour it off, or you can add a strong acid such as Sulphuric Acid to react with the mixture... Pure Gold will not react to the mixture, all the Zinc will react (in presence of enough acid) and become a salt that is soluble in water... then you just filter the gold out from the solutionHow can one separate gold from a mixture of zinc and gold? Also, how can one determine whether a white powder?
Well commenting on Paka the gas formed by the reaction of HCl to ZnS is not sulfure dioxide its hydrogen sulfide or H2S Report Abuse
Q1. Dissolve the material in a stong acid like Nitric or sulfuric acid. The Zinc should dissolve but the gold will not.
Q2. In reaction with hydrochloric acid both Zinc Sulfide and Sodium Carbonate will react- Na2CO3 forms an odorless colorless gas. ZnS will form hydrogen sulfide gas which stinks to high heaven. That would be my qualitiative test. Be careful doing this reaction in lab, as Hydrogen sulfide is a toxic gas that can be lethal. You lose the ability to smell it after exposure to high concentrations of it.
Apply heat gold will melt faster.

Go to www.ebay.com, and search for ';zinc powder';. At the moment, there are a number of sources listed, many at reasonable prices. See below for a direct link (Be sure what you buy is the metal powder, not one of the compounds. Zinc metal powder or zinc dust).
Added note: Contrary to what's been said (at least in the USA) obtaining such materials as zinc powder and most other chemicals is not at all difficult if you are a commercial or educational buyer. Lab supply houses will happily sell to commercial, industrial, or educational customers. For certain items, shipping may be difficult or expensive, however
Many suppliers are unwilling to sell chemicals to private persons (for a number of good reasons), but in general the purchase of most chemicals by individuals is still legal (at least in the USA). While the major suppliers will not sell to you as an individual, there are some specialty suppliers for many materials. Ebay is a good first place to try. Failing that, try ceramic and pottery suppliers and other sources such as www.skylighter.com or www.firefox.com.

How do you seperate zinc powder and sodium chloride?
Its simple
Just add water and warm the solution
Make sure that the water is not acidic or basic bcoz as zinc is amphoteric it dissolves in both
Now NaCl dissolves in pure water whereas zinc doesnt
Filter the soln and separate Zn and dry it to get back NaClHow do you seperate zinc powder and sodium chloride?
Add warm water to dissolve the salt and filter off Zn or decant off the salt soln.

please give as much detail as possible.Zinc plating vs. powder coating brake rotors?
First, do not coat the brake pad contact surface, that would reduce the required friction between the pad and the rotor. And that's a bad thing.
If you are looking to protect the remaining portion of the rotor, go with the zinc plating. Manufactures use zinc plating all over automobiles and often times will paint over the zinc. Powder coating won't take the heat a brake system will generate.Zinc plating vs. powder coating brake rotors?
hello. chose what the factory chose, don't go 'cute' on yourself with a newer idea.
No coating at all. They are designed to wear. Any coating is going to reduce braking efficiency.

IS Zinc and Sulphur dust added together a flash powder ?
is zinc dust plus sulphur dust a flash powder? if so what is the best ratio to make it burn fast as a pose to the ZN+S rocket fuel ratio. what is the purpose of ZN in this mixture? what is the purpose of S? by purpose i mean what is its job/ what does it do in this particular situation.
Help is much appreciated.IS Zinc and Sulphur dust added together a flash powder ?
Zinc-sulfur mixtures are some of the strangest flash powders that work. This mixture contains no oxidizing agent (which is normally required to provide supplemental oxygen to the reaction). This mixture only burns fast (as if an oxidizing agent were present) because the reaction of zinc and sulfur is forming only one product; zinc sulfide. Because a new product is being formed from both fuels, the reaction generates an enormous amount of heat and the reaction would continue even if there is no oxygen present. This fuel is not an example of an oxidation reaction in which oxygen combines with a fuel during combustion. Mixture ratios must allow for complete reaction of the fuels and for the most amount of heat to be generated.
