State whether or not these are soluble or insoluble Common salts of sodium potassium and ammonium nitrate common chloride common sulphate common carbonates and hydroxides |
Soluble soluble soluble except sodium chloride and lead chloride soluble except lead barium and calcium sulphate insoluble except for sodium potassium and ammonium |
|
|
How to make insoluble salts precipitate reactions |
Add one spatula of lead nitrate test tube and water to dissolve it make sure it’s all dissolved do the same with one spatula of sodium chloride tip the two solutions into smaller bigger give good stir to make sure it’s all mixed lead chloride should precipitate out filter out the precipitate |

Experiment to make a soluble salts using an acid and an insoluble base |
Heat the acid in water bath add base to the acid they will react to produce soluble salt keep adding till all The acid has reacted filter off excess solid to get only salt and water heat solution gently and evaporate off some of the water allow to cool and salt to crystallise |

|
Experiment to make soluble salts using acid and alkali reactions |
Measure out a set amount of acid into conical flask using Pipette Add a few drops of indicator slowly add alkali to acid until the acid is neutralise and indicators change colour carryout reaction again using exactly the same volumes of alkali and acid with no indicator the solution that remains will be salt and water |
