Question

An aqueous solution is saturated in both lithium sulfate and nitrogen gas at room temperature? what is most likely to happen if temperature increase also what would happen if temperature decrease?

a. More solid lithium sulfate is observed only

b. More nitrogen bubbles are observed only

c. More solid lithium sulfate and less nitrogen bubbles are observed

d. Less solid lithium sulfate and more nitrogen bubbles are observed

e. Nothing happens

Answer 1

Solution:

Option D (on increasing temperature)

Option C (on decreasing temperature)

In saturated aqueous solution of solute and gases, the solubility of solute increases with increasing temperature, while solubilty of gas decreases on increasing temperature.

Therefore, in the saturated solution of Lithium sulfate and N2 gas,

The solubility of N2 gas decreases on increasing temperature.

Solubility of Lithium sulfate increases on increasing the temperature.

Hence, less solid lithium sulfate and more nitogen bubbles are observed.

On decreasing temperature, more solid lithium sulfate and less nitrogen bubbles are observed.
