Question:
Which of the following statements is NOT true about solubility?
Which of the following statements is NOT true about solubility?
Show Hint
Gases that react with water, such as NH3 and CO2, do not obey Henry's law.
Updated On: Oct 1, 2026
- The solubility of gases in water usually decreases with increase of temperature.
- The solubility of gases in water usually increases with increase in pressure.
- The substances having similar inter-molecular forces are likely to be soluble in each other.
- Gases like \(\text{NH}_3\) and \(\text{CO}_2\) obey Henry's law

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
We have to find the false statement, so we check each one.
Step 2: Check (A):
Dissolving a gas in water is exothermic, so by Le Chatelier's principle solubility drops as temperature rises. TRUE.
Step 3: Check (B):
By Henry's law, solubility of a gas is proportional to its partial pressure, so it rises with pressure. TRUE.
Step 4: Check (C):
This is 'like dissolves like'. Similar intermolecular forces allow mixing. TRUE.
Step 5: Check (D):
\(\text{NH}_3\) and \(\text{CO}_2\) react chemically with water (forming \(\text{NH}_4\text{OH}\) and \(\text{H}_2\text{CO}_3\)), so their solubility does not follow Henry's law. The statement is NOT true, so (D) is the answer.
Final Answer:
The statement that is NOT true is option (D). \[ \boxed{\text{(D)}} \]
