Chapter 8, Problem 43AE

(a)

Interpretation Introduction

Interpretation:

The products have to be predicted from the reaction of ammonium phosphate with barium nitrate along with balanced formula equation.

Concept Introduction:

Double displacement reactions:  This type of reactions occurs when the cation and the anions switch between two reactants to form new products.  In order for the reaction to occur, one of the products is usually a solid precipitate, a gas or a molecular compound.

Example:  The product of the reaction between nitric acid and calcium sulphide is gaseous hydrogen sulphide and calcium nitrate.  The completed equation is,

  CaS(s)+2HNO3(aq)Ca(NO3)2(aq)+H2S(g)

Answer to Problem 43AE

The products of the reaction are ammonium nitrate and barium phosphate.  The balanced chemical equation is,

  2(NH4)3PO4(aq)+3Ba(NO3)2(aq)3Ba3(PO4)2(s)+6NH4NO3(aq)

Explanation of Solution

The reaction of ammonium nitrate with barium phosphate results in the formation of barium phosphate and ammonium nitrate.  The chemical equation is,

  (NH4)3PO4(aq)+Ba(NO3)2(aq)3Ba3(PO4)2(s)+NH4NO3(aq)

The above chemical equation is unbalanced.  The balanced equation is,

  2(NH4)3PO4(aq)+3Ba(NO3)2(aq)3Ba3(PO4)2(s)+6NH4NO3(aq)
