Summary:
- Some combinations of aqueous reactants result in the formation of a solid precipitate as a product.
- If solutions of sodium nitrate and ammonium chloride are mixed, no reaction occurs.
- Every ion is a spectator ion and there is not net ionic equation at all.
- It is useful to be able to predict when a precipitate will occur in a reaction.
- To do so, you can use a set of guidelines called the solubility rules (see Table below).Solubility Rules for Ionic Compounds in Water.
