Ncert Exercises & Solutions

According to Henry’s law, the value of Henry’s constant (K_H) for a gas is:

1.	Directly proportional to the solubility of the gas in the liquid.
2.	Inversely proportional to the solubility of the gas in the liquid.
3.	Same for all gases under identical conditions.
4.	Independent of the solubility of the gas

Hint: Use Henry's law.

Explanation: According to Henry's law p

\propto

\Rightarrow

p = K_Hx

where , x is the solubility of gases.

As value of K_H rises as solubility of gases decreases.
