Acids and Bases Chapter 32

Acids An acid is a substance that turns blue litmus paper red. Acids have a sour sharp taste. Everyday Acids Lab Acids Lemon juice (citric acid) Hydrochloric acid Rain Water (Carbonic acid) Sulfuric acid Vinegar

Bases A base is a substance that turns red litmus paper blue. Bases are the opposite of acids. Everyday Bases Lab Bases Toothpaste Sodium hydroxide Bleach Calcium carbonate Indigestion Tablets Limewater

Bases Bases that are soluble in water are called alkalis.

Neutral Some substances are neither acid or base they are said to be neutral. Water is an example of a neutral substance.

Indicators An indicator is a substance that shows, by means of colour change, whether a substance is acid or base. Examples Litmus Universal Indicator

Universal Indicator A universal indicator is used to measure the pH of a substance. Neutral solutions are pH 7 Acids have a pH less than 7 Bases have a pH more than 7

pH Scale The pH scale is a scale from 1 to 14 that tells us how strong an acid of base is. The stronger the acid the lower the pH. The stronger the base the higher the pH

pH Scale

Making a salt from an Acid an a Alkali Acid + Base = Salt + Water A salt is formed when the metal ion replaces the hydrogen in an acid. HCl + NaOH = NaCl + H20

Reactions of Acids Acid + Base = Salt + Water Hydrochloric acid + Sodium Hydroxide = Sodium Chloride + Water HCl + NaOH = NaCl + H20

Reactions of Acids Acid + Carbonate = Salt + Water + Carbon dioxide Hydrochloric acid + Calcium carbonate = Calcuim chloride + Water + carbon Dioxide 2HCl + CaCO3 = CaCl2 +H2O +CO2
