Question on: JAMB Chemistry - 2018
The solubility of the solids that dissolves in a given solvent with the liberation of heat will
A
increase with an increase in temperature
B
decrease with an increase in temperature
C
decrease with a decrease in temperature
D
not be affected by changes in temperature
Ask EduPadi AI for a detailed answer
Correct Option: A
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperature allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
