The pH scale is the measures how acidic or alkaline a substance is and runs from 0 (acidic) to 14 (alkaline) where 7 is what is known as neutral. Water often has a pH value of 7.

Also the scale is logarithmic so a substance with a pH level of 5 is ten times as acidic as something with a pH level of 6.
