The P/H Scale. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. If a pH is lower than 7 it indicates the solution is an acid. If it is above 7 it is a base or Alkaline. If a pH is a 7 it is neutral. Strong acids have lower pHs than weak acids and strong bases have lower pHs than weak bases.
In chemistry, pH (/piËËeÉªtÊ/) is a numeric scale used to specify the acidity or alkalinity of an aqueous solution. It is the negative of the logarithm to base 10 of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic. Pure water is neutral, being neither an acid nor a base.
