Which of these statements about the effect of pressure on solubility is correct?
APressure significantly affects solubility of solids in liquids.
BPressure significantly affects solubility of liquids in liquids.
CPressure significantly affects solubility of gases in liquids.
DPressure has no effect on any solubility.
Answer & Solution
Correct answer: C. Pressure significantly affects solubility of gases in liquids.
Solids and liquids are essentially incompressible, so pressure barely changes their solubility. Gases are highly compressible — their solubility in liquids rises with pressure, exactly as Henry's law predicts.
