Question

Write the complete ionic equation for the double displacement reaction that occurs when aqueous solutions of barium nitrate, Ba(NO3)2, and sodium chromate (Na2CrO4) are mixed.

2) Name the spectator ions in the chemical reaction.

3) Write the net ionic equation for this reaction

Explanation / Answer

First, this is going to be your starting balanced equation: Ba(NO3)2 (aq) + Na2CrO4 (aq) ---> BaCrO4 (s) + 2 NaNO3 (aq) 1) Ba(2+)(aq) + 2NO3(1-)(aq) + 2Na(1+)(aq) + CrO4(2-)(aq) ---> BaCrO4(s) + 2Na(1+)(aq) + 2NO3(1-)(aq) 2) The spectator ions are: 2Na(1+)(aq) and 2NO3(1-)(aq) 3) The net ionic equation is: Ba(2+)(aq) + CrO4(2-)(aq) ---> BaCrO4(s)
