1.	`4.5 g` of aluminium (at mass `27 u`) is deposited at cathode from `Al^(3+)` solution by a certain quantity of electric charge. The volume of hydrogen gas produced at `STP` from `H^(+)` ions in solution by the same quantity of electric charge will be:A. 44.8 LB. 22.4 LC. 11.2 LD. 5.6 L
Answer» Correct Answer - D (d) Equivalent mass of `Al =27//3=9` No. of equiv. of Al `=("Mass of Al deposited")/("Equivalent mass")` `=((4.5 g))/((9g" equiv"))=0.5" equiv"` No. of `"equiv"`. of `H_(2)` evolved`=0.5 "equiv"`. Volume of `H_(2)` evolved`=((0.5" equiv"))/((1.0" equiv"))xx11.2L` =5.6 L at S.T.P.
