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.
**The pH scale is a measure of the hydrogen ion concentration. It spans from 0 to 14 with the middle point (pH 7) being neutral (neither acidic or basic). Any pH number greater than 7 is considered a base and any pH number less than 7 is considered an acid. 0 is the strongest acid and 14 is the strongest base.Indicators -- An indicator is a special type of compound that changes color as the pH of a solution changes, thus telling us the pH of the solution.ny pH number greater than 7 is considered a base and any pH number less than 7 is considered an acid. 0 is the strongest acid and 14 is the strongest base.
