Triple superphosphate which contains about 46% P2O5 is produced by the reaction of phosphate rock with ortho phosphoric acid of_____________ percent concentration?
Correct answer: B. 52-54
- A. 25-28
- B. 52-54
- C. 75-80
- D. > 98
Explanation
Triple superphosphate is made by reacting phosphate rock with relatively concentrated orthophosphoric acid, commonly about 52 to 54%. This produces much more available P2O5 than single superphosphate.
