Write down the molecular and ionic equation between potassium carbonate and phosphoric acid.

Potassium carbonate react with phosphoric acid. The reaction produces potassium phosphate and carbonic acid. But carbonic acid is not stable in air, so it breaks down into carbon dioxide and water. The chemical equation for the reaction is as follows:

3 K2CO3 + 2 H3PO4 = 2 K3PO4 + 3 CO2 + 3 H2O

The ionic reaction equation is as follows:

6 K⁺  + 3 CO^2-  +  6 H⁺ + 2 PO ³⁺ =  6 K⁺ + 2 PO₄ ³⁺ + 3 CO₂ + 3 H₂O

The abbreviated ionic equation looks like this:

3 CO3 2- + 6 H + = 3 CO2 + 3 H2O.
