The last two days in class were spent on the following:
(a) using a solubility chart to determine which solutions would form precipitates
(b) writing molecular equations for double displacement (or replacement) reactions
(c) writing total (or complete) ionic equations and net ionic equations
(d) finding out the identity of solutions by using the colour ion charts and the solubility charts
Helpful Hints for Writing Molecular, Total Ionic and Net Ionic Equations
(1) Balance the molecular equation and write the states of the substances (g, l, s, aq).
(2) Substances that are dissolved in water (aqueous) are written as ions; all other substances stay in molecular form (example: CO2(g))
(3) Cancel out the spectator ions (ions that don't take part in the reaction) and write the net ionic equation.
