Copper oxidation and Hydrogen Peroxide vs. Salt Water
In my science project I put copper sheets into different liquids. Two of the liquids are Water +
hydrogen peroxide 3%)
[affil links] and another one is salt + water. The copper in the salt water turned all brown (fully oxidized?) the one in Hydrogen Peroxide turned spotty brown. Can you explain what is happening? Thank you.
