Question

Write the anode reaction, the cathode reaction and the net cell reaction in the following cells which electrode would be positive terminal in each cell? (i) Zn(s) | Zn2+ || Br2|Br- |Pt(s) (ii) Pt(s)|H2(g)|H+ (aq)||Cu2+|Cu(s)​

Answer 1

Answer:

As we know oxidation takes place at anode

i) Anode reaction: Zn --- Zn^+2 + 2e

ii) Anode reaction H2 --- 2H^+ + 2e
