Question
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 a strong base 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.(a) (ii) and (iv)(b) (i) and (iii)(c) (iv) only(d) (ii) only
Solution
The correct answer is (a) (ii) and (iv).
Here's why:
(i) The statement is incorrect because the glow of the bulb does not depend on whether the electrolyte is acidic or not. It depends on the presence of ions that can conduct electricity.
(ii) This statement is correct. Sodium hydroxide (NaOH) is a strong base and it dissociates completely in water to form Na+ and OH- ions. These ions can carry electric current, causing the bulb to glow.
(iii) This statement is incorrect without additional context. If the circuit is complete and contains an electrolyte that can conduct electricity, the bulb will glow.
(iv) This statement is correct. The glow of the bulb does depend on the type of electrolytic solution. If the solution can furnish ions for conduction, the bulb will glow. If not, it won't.
