Question

Write out the molecular equation, total ionic equation and net ionic equations for the following reactions: A solution of barium hydroxide and sulfuric acid are mixed Calcium nitrate solution is added to a solution of sodium phosphate

Answer 1

1)

Ba(OH)2 + H2SO4(aq) --->

the reaction

Molecular Reactoin

Ba(OH)2 + H2SO4(aq) --->BaSO4 + 2H2O

Total ionic

Ba+2(aq)+ 2OH-(aq) + 2H+(aq) + SO4-2(aq) --->BaSO4(s) + 2H2O(l)

Net Ionic

Ba+2(aq)+SO4-2(aq) --->BaSO4(s)

2)

Ca(NO3)2 + Na3PO4 -->

the reaction

Molecular Reaction

3Ca(NO3)2(aq) + Na3PO4(aq) --> Ca3(PO4)2(s) + 6NaNO3(aq)

Total Ionic

3Ca+2(aq) + 2NO3-(aq) + 3Na+(aq) + PO4-3(aq) --> Ca3(PO4)2(s) + 6Na+(aq) + 6NO3-(aq)

The Net Ionic

3Ca+2(aq) + PO4-3(aq) --> Ca3(PO4)2(s)
