Consider the chemical interaction between potassium carbonate salt and pentavalent phosphorus oxide. The reaction is not possible since both substances are acidic in nature and do not react with each other.

K2CO3 + P2O5 = no reaction.

Chemical reaction between calcium carbonate salt and barium hydroxide base. The result is a barium carbonate salt and a strong base, potassium hydroxide. This reaction is of the type of exchange.

K2CO3 + Ba (OH) 2 = BaCO3 + 2 KOH

Salt potassium carbonate and phosphoric acid react chemically to form potassium phosphate salt and carbonic acid.

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

The reaction of a salt of potassium carbonate and water leads to the formation of one of the strongest bases of potassium hydroxide, and carbonic acid is also formed.

K2CO3 + H2O = KOH + H2CO3.
