This experiment involves the reaction of Ba (OH) 2 with H2SO4. Which of the following gives the balanced chemical reaction used in the experiment?

Ba (OH) 2 (aq) + H2SO4 (aq) → H2Ba (s) + SO4 (OH) 2 (l)

Ba (OH) 2 (aq) + H2SO4 (aq) → BaSO4 (s) + H2O (l)

BaSO4 (s) + 2 H2O (l) → Ba (OH) 2 (aq) + H2SO4 (aq)

Ba (OH) 2 (aq) + H2SO4 (aq) → BaSO4 (s) + 2 H2O (l)

Ba (OH) 2 (aq) + H2SO4 (aq) → BaSO4 (s) + 2 H2O (l)

That's the right one.

Explanation:

You should see that this equation is balanced, not as

Ba (OH) 2 (aq) + H2SO4 (aq) → BaSO4 (s) + H2O (l)

(on reactive we have 4 H, on products, we have only 2)

Ba (OH) 2 (aq) + H2SO4 (aq) → H2Ba (s) + SO4 (OH) 2 (l)

(this is impossible, it's a nonsense)

BaSO4 (s) + 2 H2O (l) → Ba (OH) 2 (aq) + H2SO4 (aq)

(it is the same with the right one but is the other way around. The statement says, reaction of Ba (OH) 2 with H2SO4, not BaSO4 with water. Also, it is not a chemical balance.
