question_answer 38)

  In an attempt to demonstrate electrical conductivity through an electrolyte, the following apparatus (figure) was 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 becauseis 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) (i) and (iii)                     (b) (ii) and (iv)                   (c) Only (ii)                          (d) Only (iv)

Answer:

  (c) Bulb will glow becausebeing a strong base furnishesandions (which are responsible for electrical conductivity).
