A volume of 50 ml of 0.2 M $NaAl (OH)_{2} C O_{3}$ is neutralized by 0.5 N $HCl$ to form $NaCl$ , $AlC l_{3}$ and $C O_{2}$ . Volume of $HCl$ required is

Options:

Answer:

Solution:

Each $NaAl (OH)_{2} C O_{3}$ consumes 4 $H^{+}$ (2 $O H^{-}$ + $C O_{3}^{2 -}$ ). mmol salt = 50 $x$ 0.2 = 10, so meq $HCl$ = 40. Volume of 0.5 N $HCl$ = 40/0.5 = 80 ml, option (a).
