Problem

The solubility of MnSO4 in water at 20 oC is 70 g per 100 mL of water.

Is a 1.24 M solution of MnSO4 in water at 20 oC saturated, supersaturated, or unsaturated?

Solution

We’re being asked to determine if a solution is saturated, supersaturated or unsaturated.


Recall the types of saturation

Saturated Solution - A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom.

Unsaturated Solution - A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances.

Supersaturated Solution - A solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate due to an increase of temperature or pressure.


To determine the type of saturation of the solution at a constant temperature, we will determine the solubility of MnSO4 in terms of molarity and compare it with the solubility of MnSO4 in water.

Step 1: Determine the solubility of MnSO4 in terms of molarity

Step 2: Compare the solubility of MnSO4 and the concentration of MnSO4 in water
