In an attemp to demonstrate electrical conductivity through an electrolyte, the apparatus set up is given. Which among the following statement (s) is (are) correct ?

(i) Bulb will not glow because electrolyte is not acidic
(ii) Bulb will glow because HCl is strong acid and furnishes ions for conduction.
(iii) Bulb will not glow because circuit is incomplete
(iv) Bulb will not glow because it depends upon the type of electrolytic solution

Options

A. (i) and (iii)
B. (ii) and (iv)
C. (ii) only
D. (iv) Only

Answer

C

Explanation

Bulb will glow because NaOH is a strong base and strong acids or bases are good conductors of electricity as they ionise completely in aqueous solution to give ions that furnishes ions for conduction.
