Q. Solve this:
A solution contains Na₂CO₃ and NaHCO₃, 10 ml of the solution required 2.5 ml of 0.1 M H₂SO₄ for neutralization using phenolphthalein as indicator. Methyl orange is then added a further 2.5 ml of 0.2 M H₂SO₄ was mixed. The amount of NaHCO₃ in one litre of the solution is
Na₂CO₃ = 5.3 g
