 * 1) extra questions on concentration etc [[file:mrwallisscience/extra con and mol questions.pdf|extra con and mol questions.pdf]]

To write a net ionic equation:
 * 1) Experiments: Precipitation expt - [[file:mrwallisscience/precipitation expt.PDF|precipitation expt.PDF]]
 * 2) Solubility rules - [|the ausetute chem site]
 * 3) Maintaining water quality - [|Treating drinking wate]r, [|Hard water], [|Desalination], Reverse Osmosis [|Reverse osmosis 2]
 * 4) Ionic equations - The main thing about ionic equations is that they show you exactly how elements have reacted together and what states (if any) they have changed into. A net ionic equation does not show the spectator ions.
 * 5) The basics of how to write them - follow these steps -for worked examples see below
 * 6) To write the complete ionic equation:
 * 7) Start with a __balanced__ molecular equation.
 * 8) Break all soluble strong electrolytes (compounds with (aq) beside them) into their ions
 * indicate the correct formula and charge of each ion
 * indicate the correct number of each ion
 * write (aq) after each ion
 * 1) Bring down all compounds with (s), (l), or (g) unchanged.
 * 1) Write the __balanced__ molecular equation.
 * 2) Write the balanced complete ionic equation.
 * 3) Cross out the spectator ions that are present.
 * 4) Write the "leftovers" as the net ionic equation.
