• investigate the use of solubility equilibria by Aboriginal and Torres Strait Islander Peoples when removing toxicity from foods, for example:

–      toxins in cycad fruit

• Check your Understanding 4.3 and 4.4 (Chem in Focus pg. 93)

• Conduct an investigation to determine solubility rules, and predict and analyse the composition of substances when two ionic solutions are mixed, for example:

–      potassium chloride and silver nitrate

–      potassium iodide and lead nitrate

–     sodium sulfate and barium nitrate
