Question

If solubility of gas '$X$' is $0.5g{L}^{-1}$ at $1$ bar then its solubility at 3 bar pressure will be:

• A. $0.5g{L}^{-1}$
• B. $1.5g{L}^{-1}$
• C. $3.0g{L}^{-1}$
• D. $2g{L}^{-1}$

Answer 1

The correct option is B $1.5g{L}^{-1}$

If solubility of gas '$X$' is $0.5g{L}^{-1}$ at $1$ bar then its solubility at 3 bar pressure will be $1.5g{L}^{-1}$.

According to solubility rules, solubility (S) of a gas is directly proportional to pressure (P).

$S\propto P$
$\frac{S^{\prime }}{S}=\frac{P^{\prime }}{P}$

$\frac{S^{\prime }}{0.5g/L}=\frac{3bar}{1bar}$

$S^{\prime }=1.5g/L$
