A student is provided with a solution of nitric acid, HNO3\text{HNO}_3HNO3, and a solution of sodium hydroxide, NaOH\text{NaOH}NaOH.
She wants to prepare a pure, dry sample of the soluble salt sodium nitrate, NaNO3\text{NaNO}_3NaNO3.
Describe a method she could use to prepare this dry sample of sodium nitrate.
Include the essential laboratory apparatus and the steps in her procedure.
Write a balanced symbol equation for this neutralisation reaction.
The student also investigates reactions to prepare other salts.
Complete the table below to show the starting materials and the salts produced:
| Acid used | Other starting material | Salt made |
|---|---|---|
| Nitric acid | Calcium carbonate | (i) ................................................ |
| (ii) ................................................ | Copper oxide | Copper sulfate |
| Hydrochloric acid | (iii) ................................................ | Magnesium chloride |
What type of reaction occurs when sulfuric acid reacts with copper oxide?
