Question

$10c{m}^3$ of $0.1N$ monobasic acid requires $15c{m}^3$ of sodium hydroxide solution whose normality is

• A. $1.5N$
• B. $0.15N$
• C. $0.066N$
• D. $0.66N$

Answer 1

Answer: (C)

Volume of monobasic acid $=10c{m}^3$

Normality of monobasic acid $=0.1N$

Volume of $NaOH$ solution $=15c{m}^3$

Normality of $NaOH$ solution $=?$

$N_1{V}_1=N_2{V}_2$

(for monobasic acid ) (for $NaOH$ )

$10\times 0.1N=15\times N_2$

$N_2=\frac{1N}{15}=0.066N$
