4.5 g of aluminium is deposited at cathode from Al3+ solution by a certain quantity of electric charge. The volume of hydrogen produced at STP from H+ ions is solution by the same quantity of electric charge will be?
Step 1: Given data
Weight of Aluminium =4.5g
Step 2:Calculating No. of equivalents
No.of equivalents of Aluminium deposited=4.59=0.5
No.of equivalents of H2 will also be 0.5
Step 3: Deriving Volume of Hydrogen gas
Volume of H2 at STP,
