0.1914 g of an organic acidi s dissolved in about 20 ml of water. 25 ml of 0.12 N NaOH is required for the complete neutralizatioonf the acid solution. The equivalent weight of the acid is

A

`65.0`

B

`64.0`

C

`63.8`

D

`62.5`

Text Solution

Verified by Experts

The correct Answer is:
C
25 mL of 0.12 N NaOH `rarr`0.1914 g acid
`therefore " 1000 mL of 1 N NaOH "=(0.914xx1000)/(25xx0.12)=63.8`
Hence Eq.wt of acid =63.8.
