Which of the following statements is NOT true about solubility?
Options
- AThe solubility of gases in water usually decreases with increase of temperature.
- BThe solubility of gases in water usually increases with increase in pressure.
- CThe substances having similar inter-molecular forces are likely to be soluble in each other.
- DGases like NH ₃ and CO ₂ obey Henry's law
Correct answer
D. Gases like NH ₃ and CO ₂ obey Henry's law
Step-by-step solution
The solubility of gases in liquids is an exothermic process. According to Le Chatelier's principle, solubility decreases with an increase in temperature. According to Henry's law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas. Thus, solubility increases with an increase in pressure. Substances with similar intermolecular forces dissolve in each other, following the principle of 'like dissolves like'. Henry's law is applicable only to gases that do not react chemically with
