#"Concentration"="Moles of stuff"/"Volume of solution"#


And it follows if we dilute the solution, the denominator becomes bigger, and the quotient, the concentration, becomes SMALLER.

Note that when we dilute an acid, we always add conc. acid to water. Why? Because if you spit in conc. acid, it spits back. So don't spit in the acid.
