Wondering about hydrogen peroxide

AI Thread Summary
Hydrogen peroxide bleaches hair by oxidizing the melanin pigments that give hair its color. This oxidation process breaks down the dye molecules, effectively lightening the hair. The specific effects depend on the type of dye present in the hair, as different dyes react differently to the bleaching agent. Understanding the chemistry behind this process is essential for comprehending how hair color changes with the use of peroxide.

How does it bleach hair? My Chemistry professor at college told us about how chemical straightening works, but failed to explain how peroxide can change hair colour.

Thanks a bunch!

Basically hydrogen peroxide destroys dye by oxidizing it. To check details you have to check what dye is present in hair. Melanin comes to mind as a good starting point in search.

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
