(ii) and (iv)
(i) and (iii)
3)
The apparatus given in the adjoining figure was set up to demonstrate electrical conductivity? (i) Bulb will not glow because the electrolyte is not acidic. (ii) Bulb will glow because HCl is a strong acid and furnishes ions for conduction. (iii) Bulb will not glow because the circuit is incomplete. (iv) Bulb will not glow because it depends upon the type of electrolytic solution.
