Q. 2 g of metal carbonate is neutralised completely by 100mL of 0.1 (N) HCl. The equivalent weight of metal carbonate is
A) 50
B) 100
C) 150
D) 200
Explanation
(d)
Number of gram equivalents of
$HCl = \frac{100 \times 0.1}{1000} = 0.01$
Number of gram equivalents of HCl=Number of gram equivalents of metal carbonate
0.01=0.01
Therefore, mass of 1 g equivalents of carbonate salt
$= \frac{2}{0.01} = 200$g
Equivalent mass of metal carbonate=200
