Question

A solution contains Na2CO3 and NaHCO3 . 10 mL of the solution requires 2.5 mL of 0.1 M H2SO4 for neutralisation using phenolphthalein as an indicator. Methyl orange is added when a further 2.5 mL of 0.2 M H2SO4 was required. Calculate the amount of Na2CO3 and NaHCO3 in one litre of the solution.

Answer 1

solution contains na2co3 and nahco3

solution contains na2co3 and nahco3a solution contains NAHCO3 and NA2CO3 10 ml of solution require 2.5 ml of 0.1 molar H2SO4 for neutralisation using phenol phthalate as an indicator. methyl orange is added when further 2.5 ml of 0.2 ml H2SO4 is require. calculate the mass of Na2CO3 and NaHCO3 in the mixture
