The chemical equation Zn + BaSO4 -> ZnSO4 + Ba translates to English as: Zinc plus Barium Sulfate yields Zinc Sulfate and Barium.

Detailed information about the equation Zn + BaSO₄ -> ZnSO₄ + Ba
The above chemical equation describes the reaction process between zinc metal (Zn) and barium sulfate salt (BaSO₄), creating zinc sulfate salt (ZnSO₄) and barium metal (Ba).

Reaction conditions
For the reaction to occur, the necessary condition is direct contact between the reactants, along with appropriate, constant temperature and pressure. Specifically, in this case, the reaction can take place at room temperature.

The reaction process
When zinc reacts with barium sulfate, zinc will replace barium in BaSO₄ to form zinc sulfate and barium. This is an ion exchange reaction that occurs between a metal and a salt.

Observed phenomenon
Upon observation, you will see zinc powder gradually dissolves in the barium sulfate solution. When the reaction ends, zinc sulfate will be formed as a pure white solid in the solution, while barium will be released in the form of a metal.
