Answer to Question #120301 in General Chemistry for Ahad Khan

Question

An excess of dilute sulphuric acid reacts with both aqueous barium hydroxide and aqueous barium chloride. In what way are the two reactions the same?

Answer 1

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

H₂SO₄(aq)+ BaCl₂(aq) --> BaSO₄(s) + 2HCl(aq)

Both are double displacement reactions between two colorless aqueous solutions, and in both cases the white BaSO₄ precipitate is formed.
