Asked in ETEA MDCAT 2009 2009

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.
