Question

MgSO4 on reaction with NH4OH and Na2HPO4 forms a white crystalline precipitate. What is its formula? (A)  Mg(NH4)PO4  (B)  Mg3(PO4)3  (C)  MgCl2 ⋅ MgSO4  (D)  MgSO4

Tardigrade Admin · Accepted Answer

Magnesium ammonium phosphate is precipitated out MgSO4 + NH4OH + Na2HPO4 arrow Mg(NH4)PO4 downarrow + Na2SO4

Q. $M g S O_{4}$ on reaction with $N H_{4} O H$ and $N a_{2} H P O_{4}$ forms a white crystalline precipitate. What is its formula?

$M g (N H_{4}) P O_{4}$

$M g_{3} (P O_{4})_{3}$

$M g C l_{2} \cdot M g S O_{4}$

$M g S O_{4}$

Magnesium ammonium phosphate is precipitated out
$M g S O_{4} + N H_{4} O H + N a_{2} H P O_{4} \to M g (N H_{4}) P O_{4} ↓ + N a_{2} S O_{4}$
