2g of metal carbonate is neutralised completely by 100 mL of 0.1 (N) HCl. The equivalent weight of metal carbon ate is-

A

50

B

100

C

150

D

200

Text Solution

Verified by Experts

The correct Answer is:
D
No of gram-equivalent of HCl in 100 mL 0.1(N) solution `=(100xx0.1)/(100)=0.01`
So, no. of gram-equivalents of the metal carbonate=0.01
`therefore`Equivalent weight of metal carbonate`=(2)/(0.01)=200`
