Answer to Question #197527 in Chemistry for Andu

Question

19. Show how the law of conservation of mass is applied in the reaction between sulfuric acid and sodium hydroxide.

Answer 1

According to the chemical reaction between sulfuric acid and sodium hydroxide.

H₂SO₄ + 2NaOH = Na₂SO₄ + 2H₂O

All the chemical elements present in the left part of the reaction (reactants) can also be observed in the right part of the reaction (products). As a result, it can be concluded that the total mass of reactants equals the total mass of products reflecting the law of conservation of mass.
