Solubility of NaOH in water...

Solubility of NaOH in water

A

increases with increase in temperature

B

decreases with increase in temperature

C

is not affected by a change in temperature

D

first increases and then decreases with temperature.

Text Solution

Verified by Experts

The correct Answer is:
B
Dissolution of NaOH in water is an exothermic reaction
`NaOH +` Water `hArr NaOH` solution `+` Heat
As such increasing temperature shifts the equilibrium in the backward direction thus decreasing the solubility

The solubility of a crystalline compound in water is influenced by two factors. These are lattice enthalpy and hydration enthalpy. Lattice enthalpy is needed to separate the ions from the crystal lattice. At the same time hydration enthalpy is released when the ion are dissolved in water. The resultant of these two opposing tendencies guides the solubility of the compound in water. If lattice enthalpy has a greater magnitude, the compound has low solubility. In case hydration enthalpy is more, then the compound is highly soluble in water.
