  1. pH Neutral some basic stuff

  2. pH Neutral Terminology • “Acidic” and “basic” describe the two extremes of one chemical property. • “alkaline” = basic. • Neutral = A substance that is neither acidic nor basic • Mixing acids and bases will cancel out or neutralize their extreme effects. • Pure water is neutral. But when chemicals are mixed with water, the mixture can become either acidic or basic.

  3. pH Scale • The pH scale measures how acidic or basic a substance is. • pH scale ranges from 0 to 14. • pH of 7 is neutral. • pH less than 7 is acidic. • pH greater than 7 is basic. • Each number below 7 on the pH scale is ten times more acidic than the next higher number. • For example, pH 4 is ten times more acidic than pH 5 and 100 times more acidic than pH 6. • Acids have a sour taste, react with metals and can burn skin if strong enough. • For numbers above 7 each number is ten times more basic than the next lower number. • For example, pH 10 is ten times more basic than pH 9 and 100 times more basic than pH 8. • Bases have a bitter taste, do not react with metal and can also burn the skin if strong enough.
