Super Phosphate is made by:
Correct answer: A. The acidulation of phosphate rock
- A. The acidulation of phosphate rock
- B. The alkylation of phosphate rock
- C. The alcoholation of phosphate rock
- D. The alkali addition of phosphate rock
Explanation
The correct answer is A: "The acidulation of phosphate rock." Superphosphate is a fertilizer that is commonly used to provide plants with phosphorus, an essential nutrient for plant growth. It is made by treating phosphate rock with sulfuric acid in a process known as acidulation. This process converts the insoluble phosphate in the rock into a more soluble form that can be absorbed by plants.

About Green Chemistry
Green chemistry designs chemical processes that reduce waste, hazards, energy use and pollution at the source rather than treating them afterward. Its principles include prevention, atom economy, safer solvents and products, catalysis, renewable feedstocks, energy efficiency, reduced derivatisation and designing substances for degradation.
