This is part of the HSC Chemistry course under the topic of Solution Equilibria.
In this post, we 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
Remembering Solubility Rules
A neat mnemonic trick to remember the Solubility Rules. The solubility of Nitrate, Acetates, Group 1s, Sulfates, Ammoniums, and Group 17s (NAG SAG), and the exceptions, Lead, Mercury, Silver, Calcium, Strontium, Barium.
Examples of Mixing Two Ionic Substances
A worked example of the equation of a mixture of two ionic substances, Potassium Chloride and Silver Nitrate.
