Write down the molecular and ionic equations for the reactions between potassium sulfate and barium nitrate

Write down the molecular and ionic equations for the reactions between potassium sulfate and barium nitrate, between sulfuric acid and barium chloride. What is the essence of both reactions?

Potassium sulfate react with barium nitrate, resulting in the formation of barium sulfate and potassium nitrate. The reaction proceeds according to the type of exchange. barium sulfate precipitates. The chemical equation for the reaction is as follows:

K2SO4 + Ba (NO3) 2 = BaSO4 + 2 KNO3

The ionic reaction equation is as follows:

2 K + + SO4 2- + Ba 2+ + 2 NO3 – = BaSO4 + 2 K + + 2 NO3-

SO4 2- + Ba 2+ = BaSO4

The reaction of sulfuric acid with barium chloride, as a result of the reaction, barium sulfate and hydrochloric acid are formed. The reaction proceeds according to the type of exchange. barium sulfate precipitates. The chemical equation for the reaction is as follows:

H2SO4 + BaCl2 = BaSO4 + 2 HCl

2 H + + SO4 – + Ba 2+ + 2 Cl – = BaSO4 + 2 H + + 2 Cl-

SO4 2- + Ba 2 + = BaSO4.
