Question
Can you store copper sulphate solutions in a Zinc pot?
Solution
Answer:
No. Because zinc is more reactive than copper and thus holes will be developed in zinc pot.
Cu2+(aq) + Zn(s) → Zn2+ (aq) + Cu(s)
No. Because zinc is more reactive than copper and thus holes will be developed in zinc pot.
Cu2+(aq) + Zn(s) → Zn2+ (aq) + Cu(s)
