Question

Does dilution change the concentration?

Answer 1

It does so absolutely.

Explanation:

`"Concentration"` `=` `"Amount of stuff"/"Volume that stuff is dissolved in"`.

Typically, we use `"molar concentrations"` `=` `"moles of stuff"/"volume of solution"`.

If we increase the volume by dilution, we are inevitably going to REDUCE the concentration. Capisce?
