coloumb charge liberated 1 gm silver (Ag). If the charge is doubled
then the amount of liberated Ag will be:
1. | 1 gm | 2. | 2 gm |
3. | 3 gm | 4. | 4 gm |
4.5 g of aluminium (at. mass = 27 amu) is deposited at cathode from Al3+ solution by a certain quantity of electric charge. The volume of hydrogen produced at STP from H+ ions in solution by the same quantity of electric charge will be:
1. | 44.8 L | 2. | 11.2 L |
3. | 22.4 L | 4. | 5.6 L |
