A10 Insoluble Salts

Describe how to prepare insoluble salts with the precipitation method.

A soluble salt is an ionic compound that dissolves in water, an insoluble salt is one that does not dissolve in water

When the two colourless solutions KI and PbN are mixed together they form a yellow precipitate, this is the salt PbI. When know that this salt is insoluble because no matter how much we stir the solution it will not dissolve to form a clear liquid, the Lead Iodide will settle on the bottom.
