Question

What do you expect to see as the following redox reaction takes place? Mg (s) + ZnCl2(Aq) = MgCl2 (Aq) Zn (s)

Answer 1

I would expect to see

• the piece of Mg slowly become smaller

• particles of Zn gradually appear in place of the Mg

The solid Mg becomes soluble MgCl_2 and soluble ZnCl_2 becomes solid Zn.
