1.	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.
Answer» In Cell A : Sodium chloride being strong electrolyte dissociates completely and therefore current flows better. In Cell B : Acetic acid being weak electrolyte ionises only partially and therefore. only a weak current flows. In Cell C : Sugar being a covalent compound does not ionise at all and therefore, no current flows.

In Cell A : Sodium chloride being strong electrolyte dissociates completely and therefore current flows better.

In Cell B : Acetic acid being weak electrolyte ionises only partially and therefore. only a weak current flows.

In Cell C : Sugar being a covalent compound does not ionise at all and therefore, no current flows.
