  2. 2. What is a salt?  A salt is the compound formed when all or part of the ionizable hydrogen of an acid is replaced by metallic or ammonium ions.
  3. 3. Types  Normal salts  Acid salts  Basic salts  Double salts  Complex salts
  4. 4. Preparation of salts  Soluble salts  Dilute acid and metal Zn + 2HCl  ZnCl2 + H2  Alkali and acid KOH + HNO3  KNO3 + H2O  Dilute acid and insolube base H2 SO4 + CuO  CuSO4 + H2O  Dilute acid and trioxocarbonate (IV) H2 SO4 + CuCO3  CuSO4 + H2O + CO2  Recovering soluble salts from solutions Heating to dryness and crystalization
  5. 5. Preparation of salts  Insoluble salts  Double decomposition: 2 soluble compounds, one containing the metalic and the other acidic radical of the required insoluble salt are mixed together . There is exchange 0f raicals leading to precipitation of the required salt. BaCl2 + K2 SO4  BaSO4 + NaNO3  Combination of constituent elements: for preparing binary salts 2Fe + 3Cl2  2FeCl3
