A 300mg sample containing Na2CO3, NaHCO3 and NaOH and inert material either alone or in some combination was dissolved and titrated with 0.1M HCl. The titration required 24.41 mL to reach the phenolphthalein endpoint. And an additional 8.67mL to reach the methyl red end point. Determine the composition of the sample and calculate the percent of each titrated component.
