0.4 g of polybasic acid HnA (all the hydrogens are acidic) requries 0.5 g of NaOH for complete neutralisation. The number of replaceable hydrogen atoms and the molecular weight of A would be (Mw of `acid=96)`

A

`2,94`

B

`1,95`

C

`3,93`

D

`4,92`

Text Solution

Verified by Experts

The correct Answer is:
D
`mEq Acid=mEq base`
`implies(0.4)/((Mw)/(n))xx1000=(0.5)/((40)/(1))xx1000`
`impliesn=3 and H_(n)A-=96impliesA=96-3xx1=93`
