Quick student answer

How does treatment of phosphate rock with sulfuric acid to produce soluble salts for fertilisers. (Chemistry only) work?

Direct answer

In Chemistry, this page helps you answer questions about treatment of phosphate rock with sulfuric acid to produce soluble salts for fertilisers. (Chemistry only) within The Haber process and the use of NPK fertilisers. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are phosphate rock and sulfuric acid.

Key terms

  • phosphate rock: A naturally occurring mineral from which phosphate is extracted, often treated to produce soluble salts for fertilisers.
  • sulfuric acid: A strong acid used in the treatment of phosphate rock to produce soluble salts for fertilisers.

Common trap

Common Mistake in Phosphate Rock Treatment: Remember that sulfuric acid produces different soluble salts compared to nitric acid. Focus on the specific acids and their respective reactions with phosphate rock.
