Hi guys I'm studying about general chemistry in a physics class.
I've some exercices that I'm unable to solve, stuff like this:Copper can be solubilizated in water, oxidating in Cu++ form, reacting with HCrO4- in an acid environment realized by H2SO4. Write down the balanced reaction.my problem is to write (not to balance) an reduction/oxidation reaction.The copper is oxidating, so cromium or hydrogen have to reduce. I've thought about 3 different reaction.
So, in my proposal, the unbalanced reaction are:
Cu + HCrO4- -> Cu++ + Cr2O3 + H2O
Cu + HCrO4- -> Cu++ + CrO + H2O
Cu + HCrO4- -> CuCrO4 + H2
how to choose the correct one?
ciao!
