`12.5 mL` of a solution containing `6.0 g` of a dibasic acid in `1 L` was found to be neutralized by `10 mL` a decinormal solution of `NaOH`. The molecular weight of the acid is

A

150

B

120

C

110

D

75

Text Solution

Verified by Experts

The correct Answer is:
A
Dibasic acid `-= NaOH`
12.5 mL `10 mL xx 0.1 N = 1m Eq`
Strength of dibasic acid `= 6 g L^(-1)` , mEq of acid = m Eq of NaOH
`12.5 xx N = 1` m Eq , `(12.5 xx 6 xx 100)/((Mw)/(2) xx 1000) = 1 :. Mw("acid") = 150`
