In an attempt to demonstrate electrical conductivity through an electrolyte the following apparatus (figure ) set up

Which among the following statement(s) is / are correct?
(i) Bulb will not glow because electrolyte is not acidic .
(ii) Bulb will glow because NaOH is strong base and furnishes ions for conduction
(iii) Bulb will not glow becuse circuit is incomplete.
(iv) Bulb will not glow becuse it depends upon the type of electrolytic solution.

Options

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

Answer

C

Explanation

Bulb will glow because NaOH being a strong base furnishes `OH^(-) and Na^(+)` ions (which are responsible for electrical conductivity).
