(a)
Interpretation:
The law describing dissolution of oxygen gas in water has to be explained.
(a)

Explanation of Solution
The law describing dissolution of oxygen gas in water is Henry’s law.
(b)
Interpretation:
Henry’s law has to be stated.
(b)

Explanation of Solution
Henry’s law states that at a particular temperature the number of moles of gas dissolved in a liquid is directly proportional to the pressure of that gas. Also it can be stated as; solubility of the gas is directly proportional to the pressure exerted by that gas in the atmosphere that is contact with the liquid.
The mathematical expression for Henry’s law is given below.
