What is the mass of silver deposited when the charge passed is doubled, if a charge of \(10^5\) coulomb deposits 1 g of Ag?
| 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 |
