removing solution from the container

Answer 1

The concentration of a solution would remain constant after **adding solute to the solution**.

This action increases the amount of solute in the solution without changing the volume of the solution proportionally, which maintains the concentration relative to the amount of solvent present.

Adding water, evaporating water, or removing solution would change the volume of the solution, thus affecting the concentration.
