Answer:
See the answer below
Step-by-step explanation:
The concentration of a solution refers to the amount of solute that is dissolved in a particular amount of solvent.
In order to increase the concentration of salt in a solution of water, more solute (that is, the salt) would be required to be added to a fixed volume of the solution. The more the amount of the salt added, the more the concentration of the solution provided the volume remains constant.
In order to decrease the concentration of electrolytes in a solution, more solvent would be required to be added to the electrolyte while keeping the dissolved solute constant. The more the added solvent, the lower the concentration as long as the amount of solute dissolved remains constant.
