Question

Formation of barium sulfate, which is completely insoluble in water is used as the basis of a classic procedure for analyzing the amount of barium in a sample. Write a chemical equation for the double replacement, precipitation reaction of an aqueous solution of barium nitrate with concentrated sulfuric acid.

Answer 1

Answer:

Ba(NO₃)₂ (aq) + H₂SO₄ (aq) → BaSO₄ (s) + 2HNO₃ (aq)

Explanation:

The equation bellow can be explained by the dissociation of each specie:

Ba(NO₃)₂ (aq) →  Ba²⁺ (aq) + 2NO₃⁻ (aq)

H₂SO₄ (aq) →  2H⁺ (aq) + SO₄²⁻ (aq)

The reaction will lead to the formation of solid barium sulfate and nitric acid.
