Question

0.52 g of dibasic acid required 100 mL of 0.1 N NaOH for complete neutralization. The equivalent mass of acid is:

• A. 26
• B. 52
• C. 104
• D. 156

Answer 1

The correct option is B 52

Number of gram equivalent of acid = Number of gram equivalent of base

$0.52/E=0.1\times 100\times {10}^{-3}$

then E = 52

Hence, the correct option is $\text{B}$
