A 300mg sample containing Na2CO3, NaHCO3, NaOH, and inert material either alone or in some combination was dissolved or titrated with 0.10 M HCl. The titration required 24.41 mL to reach the phenolphthalein endpoint and an additional 8.67 mL to reach the methyl red end point. Na2CO3 (105. 99), NaHCO3 (84.01), NaOH (39.99). Identify the components of the sample. Show solution. Thank you.
