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.
How the pH scale works Like the Richter scale that's used to rate earthquakes, the pH scale is not linear. The intervals between numbers is logarithmic, which means every number on the scale shows ten times less H concentration than the number below. Soil with a 5 is ten times more acidic than soil with a pH of 6.
