0.126g of an acid is needed to completely neutralise 20 mL 0.1 N NaOH solution. The equivalent weight of the acid is-

Text Solution

Verified by Experts

The correct Answer is:

20 mL 0.1(N) NaOH can be neutralised by 0.126g of acid.
1000 mL 0.1 (N) acid can be neutralised by
`(0.126xx1000)/(20)g` of acid
1000mL 1(N) acid can be neutralised by
`(0.126xx1000xx1)/(20xx0.1)g=63g` of acid
Hence, the equivalent of acid=63.
