The equation BaSO4 + CaCO3 -> CaSO4 + BaCO3

The chemical equation above describes the chemical reaction process between barium sulfate (BaSO₄) and calcium carbonate (CaCO₃) to produce calcium sulfate (CaSO₄) and barium carbonate (BaCO₃). In this equation, the chemical elements barium (Ba), calcium (Ca), sulfur (S), and carbon (C), along with the chemical radicals sulfate (SO₄) and carbonate (CO₃) are preserved.

Reaction conditions: The dosage and ratio of the reactants need to be precisely controlled to ensure the balance and efficiency of the reaction. Temperature conditions, pressure, and environment can also affect the reaction.

Reaction process: BaSO₄ and CaCO₃ will begin to react upon contact, exchanging their ions to create CaSO₄ and BaCO₃. This process adjusts the balance between the reactants and the products.

Observable phenomena: Depending on the specific conditions of the reaction, there may be some observable phenomena, such as color changes, heat or light release, or the formation of a solid substance (precipitate) from a solution mixture.
