Q. Three different electrolytic cells A, B, and C are connected in separate circuits. Electrolytic cell A contains sodium chloride solution. When the circuit is completed a bulb in the circuit glows brightly. Electrolytic cell B contains acetic acid solution and in this case the bulb in the circuit glows dimly. The electrolytic cell C contains sugar solution and the bulb does not glow. Give a reason for each of these observations.

Q. Assertion :A, B & C are three electrolytic cells, connected in different circuits. Cell 'A' contains

solution, and the bulb in the circuit glows brightly when the circuit is completed. Cell 'B' contains acetic acid and the bulb glows dimly. Cell 'C' contains sugar solution, & the bulb does not glow. Reason:

N a C l

is strong electrolyte so it dissociates completely into ions. Acetic acid is weak electrolyte so it dissociates very less. Sugar is non-electrolyte so it doesn't dissociates into ions.

Q. An electrolytic cell is taken with two graphite rods inserted in it and connected to opposite terminals of a battery. An electric bulb is also introduced on the circuit. Different substances are taken in the cell and the conductivity is tested. Identify the case where the bulb glows most brilliantly.

Q. Which of the following electrolyte will help the bulb glow?

Question 20.
In an attempt to demonstrate electrical conductivity through an electrolyte, the following apparatus ( see the 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 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) (i) and (iii)
