`1g` of the carbonate of a metal was dissolved in `25mL` of `N-HCl`. Te resulting liquid `5 mL` of `N-NaOH` for neutralisation. The `Ew` of the metal `Carbonate is

A

50

B

30

C

20

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
Total `HCl implies 25 xx 1 = 25 mEq`
Excess `HCl implies 5 xx 1 = 5 mEq`
`HCl` used `implies 25 - 5 = 20 mEq`
`:. mEq` of `HCl = mEq` of carnate
`= (20)/(1000) Eq = ("Weight")/(Ew)` of carbonat `= (1)/(Ew)`
`:. = (1000)/(20) = 50`
