Write the balanced chemical equation, complete ionic and net ionic equation for the following reaction?

Potassium chromate reacting with barium nitrate

The test won’t be this bad!!!

Complete Ionic Equations

Molecular Equation:K2CrO4 + Ba(NO3)2 BaCrO4 + 2 KNO3

Soluble Soluble Insoluble Soluble

Complete Ionic Equation:2 K+ + CrO4 -2 + Ba+2 + 2 NO3

- BaCrO4 (s) + 2 K+ + 2 NO3

Net Ionic Equations

These are the same as complete ionic equations, but you should cancel out ions that appear on BOTH sides of the equation

Complete Ionic Equation: 2 K+ + CrO4 -2 + Ba+2 + 2 NO3

- BaCrO4 (s) + 2 K+ + 2

NO3-

Net Ionic Equation:CrO4 -2 + Ba+2 BaCrO4 (s)
