In the given arrangement, when electricity is passed through sodium chloride solution, the bulb glows. What does it indicate?

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. Three different electrolytic cells A, B, and C are connected in separate circuits. Electrolytic cell A contains sodium chloride solution.
