\(\mathrm{pH}\) of a \(0.1 \mathrm{M}\) monobasic acid is 2 . Its osmotic pressure at a given temperature \(T(\mathrm{~K})\) is (Given that the effective concentration for osmotic pressure is \((1+\alpha) \times\) concentration of acid \(\alpha\) is the dissociation factor
- A RT
- B 0.11 RT
- C 0.01 RT
- D 0.001 RT
Answer & Solution
Correct Answer
(B) 0.11 RT
Step-by-step Solution
Detailed explanation
\(\begin{aligned} \mathrm{pH} & =2 \\ C & =0.1=x \\ i & =1+x=1+0.1=1.1\end{aligned}\) Using formula, \[ \begin{aligned} \pi & =i C R T \\ & =1.1 \times 0.1 R T=0.11 R T \end{aligned} \]
