yes bananas have an affect from the peroxide, which causes them to fizz, and over a long period if time the banana will stiffen
Yes, it bleaches your hair if left on long enough.
Pure hydrogen peroxide certainly can cause chemical burns if it touches your skin. Hydrogen peroxide you buy from a drugstore is typically about 3% hydrogen peroxide and 97% water. As far as your skin is concerned, as long as you're not actually bathing in it it's not all that different from 100% water. You should be careful with even the dilute stuff around your eyes and mouth though; the mucous membranes are much more sensitive.
yes, as long as you use a little hydrogen peroxide to "water it down" first.
Well it wont matter because if you drink that you will die.
Hydrogen peroxide purchased from a store or science supply house has been stabilized so that expected loss due to spontaneous decomposition into oxygen and water is less than 3% per year. Without adding a catalyst, you will have to wait a very long time to collect the oxygen from a sample of hydrogen peroxide.
Yes you can although you have to be triple sure that your ear drum is not punctured or burst. You have to consult a doctor to find that out. And be sure you don't have a solid ear wax plug where the hydrogen can wiggle its way behind and with no room left to expand it can damage your earIf you are sure it is not punctured and you don't have an ear wax plug, you can put a few drops of hydrogen peroxide in the ear. This will give you a fizzing sound. After a few minutes take a clean wash cloth and turn your head over to drain the peroxide. Then put some alcohol in the ear to dry it out. Make sure you get out all the peroxide because 'left overs' will make your ears fizz for a long time
First, hydrogen peroxide you buy at the store is damaging for your hair. Second ,it is not the same as peroxide developer in hair dyes. Third, opening the hair shaft will make your color fade faster. Plus it could change the color of the dye you are putting on. The question was true. Yes hydrogen peroxide opens the cuticle of the hair to allow the dye to penetrate it. Peroxide is an alkaline substance with a base of about 9. It opens the cuticle so that the colour can be deposited in the hair. If you didn't use peroxide your colour wouldn't last long.
As many as you like, as long as you have the same amount of both.
You store lenses wet, not dry. Short term use saline solution, long term use hydrogen peroxide. To use them, take them out of the peroxide and let them sit in saline for at least 24 hours to remove all of the peroxide from them.
In the hospital setting, hydrogen peroxide is discarded 4 days after opening. It may still fizz and bubble, but it's actions are diminished. Buy the smallest bottle possible, and replace it frequently - it's cheap.
