Some household cleaners come in concentrations stronger than necessary for basic cleaning jobs. Jeremy followed the instructions on a cleaning bottle and mixed enough cleaner with 4.0 L of water to form a 1.0 M cleaning solution. After testing his cleaning solution, he decided he should double to concentration for a tough stain. Jeremy added the same amount of cleaner and then added another 4.0 L of water to his bucket. Did Jeremy succeed in making a more concentrated solution? Explain why or why not.

Answer 1

No. Jeremy did not succeed in making the solution more concentrated.

Dilution

Initially, Jeremy mixed an amount (x) of the cleaner with 4. 0 L of water making a concentration of 1.0 M.

       x/4 = 1.0 M

Thereafter, he added the same amount of (x) of the cleaner and added another 4.0 L of water:

Total amount of cleaner = x + x

                                        = 2x

Total amount of water = 4 + 4

                                      = 8.0 L

Concentration of the resulting solution = 2x/8

                                                               = x/4

x/4 = 1.0 M

Thus the concentration remains the same.
