Ammonium sulfate is a compound in fertilisers. Ammonium sulfate can be made using an industrial process or in the laboratory. In the industrial process, the following steps are used. 1. React streams of ammonia solution and sulfuric acid together. 2. Evaporate the water by passing the solution down a warm column. 3. Collect dry crystals continuously at the bottom of the column. In the laboratory, the following steps are used. 1. React ammonia solution and sulfuric acid in a conical flask. 2. Evaporate water from the solution until crystals start to form. 3. Leave to cool and crystallise further. 4. Separate the crystals using filtration. 5. Dry the crystals between pieces of filter paper. Evaluate the two methods for producing a large mass of ammonium sulfate. – 6196

1. The industrial process is done on a much bigger scale than the laboratory process.
   It is also faster and continuous, meaning it doesn’t need to be repeated.
   Reasoned judgement:
   The industrial process is better for making large amounts quickly without stopping.
