In the above image, the electrolysis of water is performed. In electrolysis the electric current is used to decompose the compound into itZs constituting compounds. During the electrolysis of water, the reaction involved is:2H2O(l) → 2H2(g) + O2(g)1. The volume of gas collected at the cathode during the electrolysis of water is:(i) Same as the volume of gas collected at the anode(ii) Half of the volume of gas collected at the anode(iii) Double of the volume of gas collected at the anode(iv) Double of the volume of gas collected at the anode2. During electrolysis, the charges carried by anode and cathode are respectively:(i) Each positive(ii) Each negative(iii) Positive, negative(iv) Negative, positive3. The gas at which electrode will blow off the burning candle ?(i) Cathode(ii) Anode4. Decomposition reaction can be carried out by which of the following?(i) Heat(ii) Light(iii) Electricity(iv) All of the above5. How many types of decomposition reaction are there?(i) 1(ii) 2(iii) 3(iv) 4 |
