Assertion :A, B & C are three electrolytic cells, connected in different circuits. Cell 'A' contains $N a C l$ 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.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
As $N a C l$ is a strong electrolyte so it dissociates completely into ions and because of these ions, it conducts electricity.

As acetic acid is a weak electrolyte so it dissociates very less and forms few ions so its solution contains both molecules and ions and it conducts electricity in a small amount.

Sugar is non-electrolyte so it doesn't dissociate into ions and its solution does not conduct electricity.

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 strong electrolyte will completely dissociate into its component ions in solution. Reason: A weak electrolyte will remain mostly undissociated in solution and dissociates very less.
