Q 28 equilibrium
Q.28. Which of the following statements are correct with respect to solubility of gas in water ?
(A) On adding more water into the solution, solubility in terms of moles disolved per litre will increase.
(B) As pressure of the gas increase solubility will decreases.
(C) As temperature of the gas increases solubility also increase
(D) None of the above.

Answer 1

Dear Student,

(A) - by adding more water reduces vapour pressure of gas results in increased solubility

(B) - by increasing pressure the gas molecules are forced into the solution hence solubility of gas molecule increases

(C) - The increase in temperature increases kinetic energy of gas in the solution results in escape of gas moles hence reduce in solubility by increasing temperature.

Hence answer is Option (A)

Regards.
