can you help with question 4, thank you.
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?
3. One erlenmeyer contains 50 mL of 0.1 M Na2CO3 solution, the other erlenmeyer contains 50 mL of 0.1 M NaHCO3 solution. Answer the following questions when both solutions are titrated with 0.1 M HC1 (F=1) solution separately: a) How much mL will be consumed if the phenolphthalein indicator is used? b) How much mL will be consumed if the methyl orange indicator is used?

14. A so-called PBS buffer (phosphate buffered saline) is prepared by according to the given protocol: ● Prepare 800 mL of distilled water in a suitable container; ● Add 8 g of NaCl to the solution; Add 200 mg of KCl to the solution; Add 1.44 g of Na₂HPO4 to the solution; Add 245 mg of KH₂PO4 to the solution; Adjust solution to desired pH (typically pH ≈ 7.4); and Add distilled water until volume is 1 L. (a) Calculate the pH of the initial solution (before pH is adjusted). (b) How many moles of acid or base are required to adjust the pH to 7.4?
