- Ba(OH)2 is Barium hydroxide, a white solid, soluble in water, colorless, odorless, and strongly alkaline.
- H2SO4 is sulfuric acid, a colorless liquid, with a strong smell, flammable, and strongly acidic.
- BaSO4 is Barium sulfate, a white solid, insoluble in water, colorless, odorless, and non-toxic.
- 2H2O is water, a colorless, odorless, tasteless liquid, non-flammable, and non-toxic.
- Reaction conditions
This reaction occurs at room temperature and standard pressure. Barium hydroxide (Ba(OH)2) and sulfuric acid (H2SO4) need to come into contact with each other to start the reaction.
- Reaction process
Ba(OH)2 and H2SO4 react with each other to produce BaSO4 and 2H2O. The strong base Ba(OH)2 will swallow the H+ ion of the strong acid H2SO4 to create water (H2O). Ba2+ will combine with SO4 (2-) to form a precipitate of BaSO4.
- Occurring phenomenon
When barium hydroxide reacts with sulfuric acid, a white precipitate of barium sulfate and water is formed.
