25 mL of a mixed solution of sodium carbonate and sodium bicarbonate required 10 mL of N//20 HCl when titrated in the presence of phenolphthalein but 25 mL of the same when titrated separately in presence of methyl orange required 25 mL of N//10 HCl. Calculate the amount of anhydrous sodium carbonate and bicarbonate in grams per litre of the solution.
