Answer 1

The concentration of a solution would remain constant after **adding solute to the solution** only in the specific case where you are simultaneously adding a corresponding amount of solvent or keep the total volume unchanged. However, in general, adding solute typically increases concentration, not keeps it constant.

On the other hand, when you **evaporate water from the container**, it decreases the volume of the solvent, which increases the concentration.

Removing solution from the container also changes the concentration because you are changing the total amount of solute and solvent.

Adding water to the solution decreases the concentration because you are increasing the volume of solvent while keeping the amount of solute the same.

Therefore, in most contexts, none of the given actions would keep the concentration constant. If we're looking for an action that generally doesn’t change the concentration, it would depend on specific amounts added or removed. However, from the options given, technically, none of these actions will stabilize the concentration under usual conditions.
