Question

Arrange the following substances in the decreasing order of their ability to dissolve 100 g of salt.

• A. Water at $100°C$
• B. Water at $40°C$
• C. Water at $50°C$
• D. Water at $80°C$

Answer 1

Solubility of a substance decreases with a decrease in temperature. So the maximum amount of salt would be dissolved in water at 100 ${}^{\circ }$C than at 40 ${}^{\circ }$C.
