Question 5: A 200.00-mL sample containing possible mixture of NaOH, Na2CO3, and/or NaHCO3 is diluted to form 250.00 mL solution. 50.00 mL aliquot of this solution is titrated with 0.2011 M HC1, requiring 22.20 mL to reach the phenolphthalein endpoint. A second 50.00 mL aliquot requires 49.80 mL of the titrant to reach the methyl orange endpoint. Determine the composition and the concentration of the solute in the original solution.

explain each of the following cases. a) when we treat 1 mol / liter of hydrochloric acid, the pH increases. There comes a cast that the pH reaches a certain value and does not change anymore. Why does this happen? b) Methyl orange can be used to determine the final titration point of nitric acid with ammonia solution, while phenophthalein is not used in this case. Why? c) pH of 10-8 mol / l HCl is not 8. Why?
