Question

Henry’s law is a relation between

• A. pressure and solubility
• B. temperature and pressure
• C. volume and solubility
• D. pressure and volume

Hint:

Henry’s law explains why carbonated drinks lose dissolved gas when the bottle is opened.

Answer 1

The Correct Option is A

Step 1: State Henry’s law.
Henry’s law states that at constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid.
Step 2: Express the relationship mathematically.
\[ S \propto P \] where \(S\) is solubility and \(P\) is pressure.
Step 3: Conclusion.
Thus, Henry’s law establishes a relationship between pressure and solubility.
