Question

Which acid is used in the manufacture of the fertilizer superphosphate?​

Answer 1

Answer: Sulfuric acid

Explanation: Sulfuric acid (H2SO4) is important in the production of fertilizers (e.g., ammonium sulfate (sulfate of ammonia), (NH4)2SO4, and superphosphate, Ca(H2PO4)2, which is formed when rock phosphate is treated with sulfuric acid). Sulfuric acid is manufactured at the site using the well-known contact process.

Answer 2

Answer:

The acid is used for the  manufacture of the fertilizer superphosphate is  Sulfuric acid (H2SO4)

Explanation:

• Sulfuric acid (H2SO4) is important in the production of fertilizers (e.g., ammonium sulfate (sulfate of ammonia), (NH4)2SO4, and superphosphate, Ca(H2PO4)2, which exists formed when rock phosphate is treated with sulfuric acid). Sulfuric acid exists manufactured on the spot using the well-known contact process.
• In New Zealand and Australia, this is supplied mainly as superphosphate fertilizer. Superphosphate is manufactured by reacting the insoluble phosphate rock with sulfuric acid to form a mixture of soluble mono-calcium phosphate and calcium sulfate (approximately 9% phosphorous) which can be used by plants.

Hence, The acid is used for the  manufacture of the fertilizer superphosphate is  Sulfuric acid (H2SO4)
