Question

Epsom salts (magnesium sulfate) have a solubility of 26.2 grams. If you dissolved 26.0 grams of Epsom salts in 100 g of water at 20 degrees Celsius, what type of solution would this be?
supersaturated solution

equilibrium solution

saturated solution

unsaturated solution

Answer 1

Answer:

unsaturated solution

Explanation:

Given: Epsom salts have a solubility 26.2 grams.

By definition,Solubility is the maximum amount of solute that can be dissolved in 100 g of water.

A solution is called saturated solution when the concentration of solute becomes equal to its solubility.

If the concentration of solute is less than solubility it is called unsaturated solution.

In this case: solubility is 26.2 grams.

If we dissolve 26 grams of Epsom salt in 100 g of water , concentration of solute is less than the solubility(26.2 g in 100 g  of water) , hence it is an unsaturated solution.
