Question

unit 3 properties > lesson 6 solutes and solvents back to intro page solutes and solvents quick check after which action would the concentration of a solution remain constant? (1 point) adding water to the solution evaporating water from the container removing solution from the container adding solute to the solution

Explanation:

Step1: Understand concentration formula

Concentration = $\frac{\text{Amount of solute}}{\text{Amount of solution}}$.

Step2: Analyze adding water

Adding water increases amount of solution, decreases concentration.

Step3: Analyze evaporating water

Evaporating water decreases amount of solution, increases concentration.

Step4: Analyze adding solute

Adding solute increases amount of solute, increases concentration.

Step5: Analyze removing solution

Removing solution keeps ratio of solute - to - solution the same, concentration constant.

Answer:

removing solution from the container
