Acids Reaction: þ Produce H + (as H 3 O + ) ions in water Produce H + (as H 3 O + ) ions in water Produce H + (as H 3 O + ) ions in water Acids contain H + cations, that react with metals and produce H gas. Acids contain H + cations, that react with metals and produce H gas. HCl + Na = NaCl + H (g) HCl + Na = NaCl + H (g) Acid + Metal = Product + H Gas Acid + Metal = Product + H Gas

Acids Properties: Acids taste sour. Acids turn Litmus paper REDLitmus paper þ Corrode metals þ React with bases to form salts and water

Bases Reaction: Bases contain an OH - anion, that react with acids, producing liquid H 2 O. Bases contain an OH - anion, that react with acids, producing liquid H 2 O. HCl + NaOH = H 2 O + NaCl HCl + NaOH = H 2 O + NaCl Acid + Base = Water + Product Acid + Base = Water + Product See movie (on hardrive) on the Internet movieInternetmovieInternet

Bases Properties: Bases taste bitter. Bases feel slippery. Bases turn Litmus paper BLUE.Litmus paper Produce OH - ions in water Taste bitter, chalky Are electrolytes React with acids to form salts and water
