What substances can react with barium sulfate? 1. barium and sulfur oxide (4) 2. solutions of barium chloride and sodium sulfate 3. solutions of barium hydroxide and potassium sulfate 4. barium, sulfur and water.
Obtaining a salt of barium sulfate is possible according to assignment No. 2, No. 3. We compose the reaction equations:
BaCl2 + Na2SO4 = BaSO4 + 2NaCl – ion exchange reaction;
Ba (OH) 2 + R2SO4 = BaSO4 + 2KOH – ion exchange reaction.
The essence of the ongoing reactions of ion exchange is that barium sulfate is formed in the form of a white precipitate.
Abbreviated ionic equation:
Ba2 + + SO42- = BaSO4
Barium compounds are used in glass production and signal flares.
