Soluble salts can be made by reacting an acid with a metal hydroxide, a metal oxide, or a metal carbonate.
Insoluble salts can be made by using a precipitation reaction.
Complete the table to show which acid or metal compound is used to make each salt listed.
For each metal compound, state whether it would be used as a solid or in aqueous solution.
| Salt made | Acid used | Metal compound Name | Solid or aqueous solution |
|---|---|---|---|
| copper(II) sulfate | copper(II) carbonate | ||
| lead(II) chloride | hydrochloric acid | aqueous solution | |
| potassium nitrate | potassium hydroxide |
An acid is a source of hydrogen ions, H+\text{H}^+H+.
Write an equation to show the ions formed when hydrochloric acid is dissolved in water.
Lead(II) iodide is an insoluble salt that can be prepared by reacting lead(II) nitrate with potassium iodide.
Describe how you would prepare a pure, dry sample of lead(II) iodide starting from solid lead(II) nitrate and solid potassium iodide.
