If 10 cm 3 of distilled water is added to 10 cm3 of an aqueous salt solution, the concentration of the solution

Answer Details

If 10 cm³ of distilled water is added to 10 cm³ of an aqueous salt solution, the total volume of the resulting solution is 20 cm³. However, the amount of solute (the salt) in the solution remains constant, while the amount of solvent (the water) increases. Therefore, the concentration of the solution decreases since the same amount of solute is now present in a larger volume of solution. So, the correct option is: the concentration decreases.
