Q949
Triple super phosphate contains
A.
40 - 48% P2O5
AnswerB.
16 - 20% P2O5
C.
60% P2O5
D.
25 - 30% P2O5
Answer: Option A
Solution
Answer: Option A
Solution:
Triple super phosphate contains 40 - 48% P2O5.Triple superphosphate is a component of fertilizer that primarily consists of monocalcium phosphate, Ca(H2PO4)2. Triple superphosphate is obtained by treating phosphate rock with phosphoric acid.
Triple superphosphates [TSPs, Ca(H2PO4)2·H2O] were produced by exothermic reactions of oyster shells and different concentrations of phosphoric acid in a molar ratio of 1 : 2.
