Question

0.126 g of an acid requires 20ml of 0.1N NaOH for complete neutralisation. Eq wt of the acid is?

Answer 1

Equivalent weight of acid is 63

Explanation:

A substance's equivalent weight is defined as that substance weight displaces or combines with 1 part by hydrogen weight or 8 parts by oxygen weight or 35.5 part by chlorine weight.

From the given,

Weight of acid = 0.126 g

Volume = 20 ml

Let's convert into liters

$\text{Volume} =\frac{20}{1000} L$

For neutralization, 20 ml of 0.1N NaOH requires 0.1N acid.

Normality of acid = 0.1N

Let's calculate the acid's equivalent weight.

$\text{Equivalent weight} =\frac{\text { Weight of acid }}{\text {Normality} \times \text {Volume}}$

$=\frac{0.126 \times 1000}{0.1 \times 20}=63$

Therefore, equivalent weight of acid is 63.
