25. At room temperature the solubility of table salt in water is 359 g/L. If a solution was prepared at a high temperature with 20 g of table salt in 100 mL of water and then cooled back to room temperature, which of the following would best describe the solution? (Assume no precipitate has formed.)

A.

A saturated solution

B.

An unsaturated solution

C.

A supersaturated solution

D.

An incomplete solution

E.

A dominant solution

A.

A saturated solution

B.

An unsaturated solution

C.

A supersaturated solution

D.

An incomplete solution

E.

A dominant solution

Explanation / Answer

Lets find the concentration of solution

concentration = 20 g/100 mL

= 20 g / 0.100 L

= 200 g/L

Since the concentration is less than solubility, the solution is unsaturated solution

Answer: unsaturated solution
