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