() A solution contains NaOH, Na CO, and NaHCO3, either alone or in compatible combination, was titrated with 0.2 M HCI. Titration of a 50 mL portion required 15 mL of HCl to reach phenolphthalein endpoint. Titration of a second 50 mL portion required 42 mL of the HCI to reach bromocresol green endpoint. Identify the mixture components and calculate the molar concentration of each component in the original solution. (

() A solution contains NaOH, NażCO3 and NaHCO3, either alone or in
compatible combination, was titrated with 0.2 M HCI. Titration of a 50 mL
portion required 15 mL of HCl to reach phenolphthalein endpoint. Titration of
a second 50 mL portion required 42 mL of the HCl to reach bromocresol green
endpoint. Identify the mixture components and calculate the molar
concentration of each component in the original solution.
