11.3 The reactions of acid & bases
name of salt depend on acid
hydrochloric acid ---> chloride
sulfuric acid --> sulfate
nitric acids ---> nitrate
typical acid reaction
acid + metal ---> salt + hydrogen
acid + base ---> salt + water
metal oxides & hydroxides : act as bases
soluble bases --> alkali
acid + carbonate ---> salt + water + carbon dioxide
reactions of bases
calcium / potassium / sodium hydroxide + ammonium salts---> metal salt + water + ammonia
ammonia gas-- damp red litmus paper
Neutralisation
react with acid form salt and water
reduce acidity in soil
crushed limestone
lime (calcium oxide)
slaked lime (calcium hydroxide)
no electron transferred , not a redox reaction
redox reaction
acid + metal
