Q. 7

State Henry’s Law and write its two application?

Chemistry - Board Papers All India - 2019 BVM-1

Answer :

Henry’s law states that “The Solubility of Gas is proportional to its partial pressure”. It can be written mathematically as follows

P=K_h*X

Here the importance of the Henry’s constant is as follows

(1) Increase solubility of Co₂ in soft drinks.

(2) During Scuba Diving

(3) Environmental Chemistry
