What occurs when aqueous aluminum nitrate, A l ( N O 3 ) 3 , reacts with aqueous ammonium phosphate, ( N H 4 ) 3 P O 4
Nikolay [14]

Answer:

You make aluminum phosphate which is an insoluble salt, so a precipitated is formed.

Explanation:

First reagent: Al(NO₃)₃

Second reagent: (NH₄)₃PO₄

This is the reaction:

Al(NO₃)₃  (aq) +  (NH₄)₃PO₄  (aq) → AlPO₄ (s) ↓ +  NH₄NO₃ (aq)

Al³⁺ (aq)  +  PO₄⁻³ (aq)  ⇄  AlPO₄ (s) ↓     Kps

Salt from phosphate is formed.
