Question

4.5 g of aluminium (at mass 27 amu ) is deposited at cathode from Al 3 + solution by a certain quality of electric charge. The volume of hydrogen produced at STP from H + ions in solution by the same quantity of electric charge will be:NEET 2005

TestHub · Accepted Answer

We know that, I Faraday charge liberates 1 eq. of substance. eq. wt. of AI = eq. wt wt.of Al ​ = 9 4.5 ​ = 0.5 no. of Faraday required = 0.5 no. of eq. of H 2 ​ produce = 0.5 eq. Volume occupied by 1 eq. of H 2 ​ = 2 22.4 ​ = 11.2 Volume occupied by 0.5 eq = 11.2 × 0.5 = 5.6 litre at STP
