Ncert Exercises & Solutions

The value of Henry's constant, K_H, is:

1.	Greater for gases with higher solubility.
2.	Greater for gases with lower solubility.
3.	Constant for all gases.
4.	Not related to the solubility of gases.

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.
