Given below are two statements.
Statement I For a solution of 
in water, the van't Hoff factor ( 
) is greater than 1 .
Statement II The solubility of gas is directly proportional to the pressure over the solutions at a given temperature.
In the light of the above statements, choose the correct answer from the options given below .
Text Solution
Verified by ExpertsB
For a solution of 
in water, the van't Hoff factor (i) is greater than 1 due to hydrolysis.
As the number of particles increases due to hydrolysis, the van't Hoff factor is more than 1 . Hence, statement 
is true. The solubility of gas in liquid is directly proportional to the pressure over the solutions at a given temperature. This is according to Henry's law. Hence, statement II is also true.
