titration an impure mixture containing sodium carbonate and sodium hydroxide, using two indicators. If 1g of the sample needed 30ml of 0.2N HCI solution to reach the neutral point with respect to the p.p indicator. And 13.5ml of the same acid to reach the equivalence point with respect to the M.O. What is the composition of the mixture and what are the percentages of its components?
