Question

an aques solution of nickel sulphate to was electro electrode and using nikal electrodes observe the diagram and answer the followingppp
1 what do you observe at anode and cathode respectively
2 name the cations and remains as for spectator ions is the solution
3 the equation for reaction at anode​

Answer 1

Answer:

i) Cathode - silvery metal deposited or coated or sticks / nickel or metal is deposited or coated or sticks / silvery deposit/increases in size or mass

Anode - Size decreases / reduction in mass / Anode dissolves / Anode Diminishes / Anode loses weight

(ii) Hydrogen ion or H+ or hydrogen

(iii) 1 or Ni → Ni2+ + 2e-
