Single super phosphate contains

A. 16 - 20% P₂O₅

B. 20 - 25% P₂O₅

C. 25 - 35% P₂O₅

D. 40 - 48% P₂O₅

Answer: Option A

Solution(By Examveda Team)

Single super phosphate contains 16 - 20% P₂O₅.
It contains 3 major plant nutrients namely Phosphorus, Sulphur and Calcium along with traces of many micro-nutrients.
Traditional routes for extraction of phosphate rock using sulfuric acid give single superphosphate, an approximate 1 : 1 mixture of Ca(H₂PO₄)₂ and CaSO₄ phosphogypsum).
It consists of approximately 16 - 20% of phosphorus and 11% of sulphur.
