Metathesis Reactions (aka Double Replacement Reactions)
Metathesis Reactions (Double Replacement)
Objectives
- Predict the products of and write balanced reactions for both precipitation and neutralization metathesis reactions.
The Bad Prom Date Analogy
Represented as: AX + BY \rightarrow AY + BX
You will be responsible for predicting the products of two types of metathesis reactions: precipitation and neutralization.
Precipitation Reactions
- Produce a solid product known as a precipitate (ppt).
Neutralization Reactions
- Occur when acids are reacted with bases.
- The products are usually water and a salt, although some neutralizations produce a gas and a salt.
Examples of Metathesis Reactions
- Silver nitrate solution reacts with aqueous potassium chloride.
- Solutions of barium chloride and potassium sulfate are mixed.
- A solution of iron (III) sulfate is mixed with a solution of lithium hydroxide.
- Potassium nitrate (aq) is reacted with sodium acetate (aq).
- Hydrochloric acid reacts with a solution of sodium hydroxide.
- Solid magnesium hydroxide pellets are mixed into a solution of nitric acid.
- Acetic acid reacts with a solution of sodium hydroxide.
- Solid magnesium oxide is mixed into a solution of nitrous acid.
- Sulfuric acid is reacted with aqueous lithium hydroxide.
- Solid calcium oxide powder is combined with a solution of hydrochloric acid.
- Solutions of hydrofluoric acid and barium hydroxide are combined.
- A sample of solid copper (II) hydroxide is added to a solution of hypochlorous acid.
- Solid sodium sulfide is reacted with a warmed solution of hydrochloric acid.
- Solid magnesium sulfide is mixed into aqueous phosphoric acid.
- A solution of sodium carbonate is neutralized with a solution of hydrochloric acid.
- Calcium carbonate chunks are covered with a solution of dilute sulfuric acid.
- Baking soda (sodium bicarbonate) is saturated with a vinegar solution (acetic acid) to make a model volcano.
