11
Q
Metal displacement reactions.
A
Metal and metal ion switch places if the metal is higher on the activity series.
12
Q
List the steps in writing an equation producing a precipitate.
A
- Predict the products by switching the places of the cations and anions. E.g. CuSO4 + NaOH -> CuOH + Na SO4
- Consult solubility rules to see whether the products are soluble, write the subscript (s) on the insoluble product, and the subscript (aq) on the rest.
- If they are both soluble and no precipitate forms write no reaction.
