Question

0.01 M $C{H}_{3}COOOH$ has 4.24% degree Of dissociation, the degree of dissociation of 0.1 M $C{H}_{3}COOH$ will be

• A. 1.33%
• B. 4.24%
• C. 5.24%
• D. 0.33%

Answer 1

The correct option is A 1.33%

Since, the acid is same, its acid dissociation constant is same.
$\frac{{\alpha }_1}{{\alpha }_2}=\sqrt{\frac{c_2}{c_1}}$
$\frac{{\alpha }_1}{4.24}=\sqrt{\frac{0.01}{0.1}}$
${\alpha }_1=1.33$%.
