Explain, why during the electrolysis of copper sulphate using copper electrodes, the colour of solution does not fade?
What is meant by the term 'electrolyte'?
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.
Give appropriate scientific reasons for the following statement :
The electrical conductivity of acetic acid is less in comparision to the electrical conductivity of dilute sulphuric acid at a given concentration.
State the observation at the anode and at the cathode during the electrolysis of :
Copper sulphate solution using copper electrodes.
Distinguish by a chemical test, ammonium sulphate and sodium sulphate.
