Question

What are two ways to make a saturated solution of NH3 in 100.g H20 at 60°C become unsaturated?

Answer 1

To make a saturated solution of NH3 in water at 60°C unsaturated, one can increase the temperature or dilute the solution with more water.

Step-by-step explanation:

Two ways to make a saturated solution of NH3 in 100 g H2O at 60°C become unsaturated are:

1.Increase the temperature: If the temperature is raised above 60°C, the solubility of NH3 in water increases, allowing more NH3 to dissolve, which results in an unsaturated solution. This aligns with the principle that solubility generally increases with temperature for most solids and gases in liquids.

2.Dilute the solution: By adding more water to the solution, the concentration of NH3 decreases. Thus, if the solution contained the maximum amount of NH3 that could be dissolved at 60°C, by increasing the amount of water, the NH3 concentration is reduced, and the solution becomes unsaturated.

Answer 2

The two ways to make a saturated solution are 1 reducing the temperature of the solution and Adding more solute.
