Question
A current of 0.965 ampere is passed through 500ml of 0.2 M solution of ZnSO4 for 10 minutes. The molarity of Zn2+ after deposition of zinc is
1. 0.1M
2. 0.5M
3. 0.8M
4. 0.194M
Read 1 Solution.
first found how much zn2+ will be deposit then find mass from 500ml , o.2 M , then find their diff(mass which is not deposit ) then find mlarity of this mass ,vol will be500ml = 500/1000 L
