how do u solve this?
a solution contains Na2CO3 and NaHCO3.10 ml of the solution requires 2.5 ml of 0.1Mfor neutralisation using phenolphthalein as indicator. methyl orange is then added when a further 2.5 ml of 0.2 MH2SO4was required. calculate amount of Na2CO3 and NaHCO3in 1 l of solution.
i'd be grateful if someone answered..........
