State the observations at the anode and at the cathode during the electrolysis of copper sulphate solution using copper electrodes.
Name the product formed at the anode during the electrolysis of acidified water using platinum electrodes.
Name a base which is a weak electrolyte.
Explain the term : Anode mud
Al+3 ,Cu+2 ,Na+ ,Zn+2 ions are present in aqueous solution, such that the concentration of ions is same, write the order of discharge of ions.
Explain, why copper though a good conductor of electricity is, a non- 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.
