Introduction to Precipitation Reactions
- Precipitation reactions occur when two aqueous solutions react to form an insoluble solid, known as a precipitate.
- Example: Mixing aqueous copper(II) sulfate (CuSO4) with aqueous sodium hydroxide (NaOH) forms solid copper(II) hydroxide (Cu(OH)2).
Identifying Precipitates
- Visual Observation: A precipitate appears as a solid that settles at the bottom of the reaction vessel.
- Example: Blue solid copper(II) hydroxide (Cu(OH)2) forms when copper(II) sulfate and sodium hydroxide react.
- Solubility Rules: Referencing solubility rules helps predict whether a precipitate will form.
- Example: Most hydroxide salts (OH-) are slightly soluble, indicating that only a small amount dissolves.
- Solubility Charts: Charts can be used to determine the solubility of specific ions.
- Example: Copper(II) ion (Cu2+) and hydroxide ion (OH-) combination indicates insolubility (Cu(OH)2).

FAQs on Forming precipitates - Year 7 Chemistry (Cambridge)
| 1. What are precipitation reactions? |  |
Ans. Precipitation reactions are chemical reactions in which an insoluble solid (precipitate) forms when two solutions are mixed together.
| 2. How do you know if a precipitation reaction will occur? | |
Ans. A precipitation reaction will occur if the products formed are insoluble in water. This can be determined by looking at solubility rules for common ions.
| 3. Can you give an example of a precipitation reaction? | |
Ans. One example of a precipitation reaction is the reaction between silver nitrate and sodium chloride, which forms a white precipitate of silver chloride.
| 4. How can you separate a precipitate from a solution? | |
Ans. A precipitate can be separated from a solution by filtration. The solid is collected on filter paper, washed with water, and then dried.
| 5. Are all insoluble compounds considered precipitates in a reaction? | |
Ans. Not all insoluble compounds formed in a reaction are considered precipitates. Precipitates are specifically formed during a precipitation reaction when two solutions are mixed together.
