6. A mixture that weighed 1.0105 g may contain NaOH, Na,CO; and NaHCO. It was dissolved in 100 mL of water. It was analyzed by titrating three 25 mL aliquots of the sample with a 0.0902 M HC1 solution, using Phenolphthalein and Bromcresol Green as indicators. The volumes of acid necessary to achieve the color change of the indicators are detailed below: Vt (mL) 37.9 38.0 | Vf tmL) Aliquot 1 15.9 Aliquot 2 16.1 Aliquot 3 15.8 38.1 a) Mention which components exist in the mixture. b) Calculate the percentage of each component in the mixture.
