Salts By Amy Badger

Acid + Metal = Salt + Hydrogen For example Sulphuric acid + Potassium hydroxide = Potassium sulphate + Hydrogen

Acid+ Base = Salt + Water For example Nitric acid + Potassium oxide = Potassium nitrate + water

Acid + Alkali = Salt + Water For example Hydrochloric acid + Potassium hydroxide = Potassium sulphate + Water

Acid + Carbonate = Salt + Water + Carbon Dioxide For example Sulphuric acid + Potassium carbonate = Potassium sulphate + Water + Carbon Dioxide

Precipitation Precipitation is when you make insoluble salts by reacting two soluble salts. The salt is formed as a solid. This reaction is useful when we want to remove metal ions from polluted ions. For example: Lead nitrate + sodium chloride = Lead chloride+ sodium nitrate

Solubility of salts All sodium, potassium and ammonium salts are soluble in water. All nitrates are soluble in water. All sulphates are soluble in water except: lead, barium and calcium sulphate. All chlorides are soluble In water except silver and lead chloride. All carbonates are insoluble in water except sodium, potassium and ammonium carbonate.

Questions An acid plus a base equals what? How do you make a salt, water and carbon dioxide? Precipitation is when you make insoluble salts by reacting what? Are nitrates soluble? Is Lead sulphate soluble?

Answers Salt + Water Acid + Carbonate Two soluble salts Yes No
