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.

Substances with a pH lower than 7 are acidic, those with a pH of 7 are neutral and those with a pH greater than 7 are alkaline.he chemical properties of many solutions enable them to be divided into three categories-acids, alkalis and neutral solutions. The strength of the acidity or alkalinity is expressed by the pH scale. 1  solutions with a pH less than 7 are acidic.
