Homework Statement
We throw clean Zn in a HCl solution and see that nothing happens. We add 2-3 drops CuSO4 and some kind of gas starts to release. Why dos this happen? Write the equation
Homework Equations
Zn+HCl->ZnCl2+H2
The Attempt at a Solution
I know that equation and also:
Zn+CuSo4->ZnSo4+Cu
But why doesn't H2 release in the first experiment? Maybe because it is too clean. COuld you also hep me with the general equation?
