Solution(By Examveda Team)

Single super phosphate (SSP) is produced by reacting rock phosphate with sulphuric acid (H₂SO₄). The chemical formula of SSP is Ca(H₂PO₄)₂ · 2H₂O (Monocalcium Phosphate Dihydrate). In SSP, the phosphorus is in the form of P₂O₅ and contains 16% P₂O₅.
SSP is the most popular phosphatic fertilizer after DAP containing 3 major plant nutrients namely phosphorus, Sulphur and Calcium along with many micronutrients.
