Precipitation reactions

Salts and their solubility in water.

Each acid has its own family of salts.

  • Sulphuric acid produces sulphates
  • Nitric acid produces nitrates
  • Hydrochloric acid produces chlorides

Salts are very often water soluble, if you stir them in water they dissolve and go into solution. Flick through the presentation to slide 4 and use the solubility rules to do the homework exercise. You can watch a precipitation reaction after slide 5.


Put the date in your book. Copy in the list and predict whether each salt is soluble in water or insoluble. The first one is done for you
