Question

Statement-1: Reaction of disodium hydrogen phosphate with magnesium sulphate in presence of ammonium hydroxide gives a white crystalline precipitate.
Statement-2:Insoluble magnesium ammonium phosphate is formed.
A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer 1

Correct Answer - A
`MgSO_4` on reaction with `Na_2HPO_4` in presence of `NH_4OH` gives white precipitate of `Mg(NH_4)PO_4`
`MgSO_4 + Na_2HPO_4 + NH_4OH to Mg(NH_4)PO_4 darr + Na_2SO_4+H_2O`
