| Explain the process of producing a fertiliser from the reaction of an acid and an alkali. Step 1 | The alkali is titrated with the acid using an indicator to find out the quantities needed before the main batch is made, this is repeated until the results are consistent. |
| Step 2 | Although the acid and alkali have fully reacted to produce a neutral solution of ammonium fertiliser. However, the this batch is contaminated with universal indicator. |
| Step 3 | The titration results are used to repeat the experiment, now using the correct quantities. |
| Step 4 | The dissolved fertiliser is heated to evaporate most of the water off, then left for the remaining solution to crystallise. The crystals are then filtered off. |
