CSS Physical and Inorganic Chemistry P-I QUESTION #1426
Question 1
The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This statement is based upon:
  • Raoult's law
  • Henry's law✔️
  • Kohlrausch's law
  • None of these
Correct Answer Explanation
Henry's Law states: \(C = k_H \cdot P\), where \(C\) is the concentration of dissolved gas, \(P\) is the partial pressure of the gas above the liquid, and \(k_H\) is Henry's law constant. Raoult's law relates vapour pressure of solutions; Kohlrausch's law relates molar conductivity of electrolytes at infinite dilution.
