Question

(NH4)3PO4 + Pb(NO3)4. Pb3(PO4)4 + NH4NO3

Answer 1

4(NH₄)₃PO₄ + 3Pb(NO₃)₄  →  Pb₃(PO₄)₄ + 12NH₄NO₃

Explanation:

   (NH₄)₃PO₄ + Pb(NO₃)₄  →  Pb₃(PO₄)₄ + NH₄NO₃

Balancing this equation;

  We simply use a mathematical approach by solving simple algebraic equations.

       a(NH₄)₃PO₄ + bPb(NO₃)₄  →  cPb₃(PO₄)₄ + dNH₄NO₃

a,b,c and d are the coefficients that will balance the equation;

   Conserving N:    3a + 4b = 2d  equation 1

                        H:    12a = 4d

                        P;      a = 4c

                        O;      4a + 12b = 16c + 3d

Let us make a = 1;

                      c = $\frac{1}{4}$

                      d = 3

solving for b;

               from (i);    4b = 2d -3a = 2(3) - 3(1) = 3

                                b = \frac{3}{4}

Now multiply a, b, c and d by 4;

                   a = 4 , b = 3 , c= 1 and d = 12

                4(NH₄)₃PO₄ + 3Pb(NO₃)₄  →  Pb₃(PO₄)₄ + 12NH₄NO₃
