Assetion (A) When methyl alcohol is added to water, boiling point of water increases.
Reason (R) When a volatile solute is added to a volatile solvent elevation in boiling point is observed.
In an exothermic process, solubility _______ with an increase in temperature.
At equilibrium the rate of dissolution of a solid solute in a volatile liquid solvent is ................
(a) less than the rate of crystallisation
(b) greater than the rate of crystallisation
(c) equal to the rate of crystallisation
When a solid solute is added to solvent, some solute dissolves and its concentration increases in solution. This process is known as

[Given that the solubility product of Mg(OH)2 is 1.8×10−11]
- 2×10−8 M
- 1×10−13 M
- 1.8×10−9 M

Solubility of sodium chloride solution at room temperature is of water. of saturated solution of Sodium chloride was allowed to evaporate when of water evaporated. Calculate the amount of crystals deposited due to evaporation.
When common salt is dissolved in water:
Melting point of solution increases
Boiling point of solution increases
Boiling point of solution decreases
both melting .point and boiling point decreases
