4. What volume, in mL of 0.197 M HCIO4 needs to be added to 187.2 mL of 0.546 M RBCIO to achieve a solution with a pH of 7.35. Note: the pkb of RBCIO is 6.47, you may assume the 5% approximation holds, and you may assume that the volumes are additive.

... 2@ 48 TO Time left 0:24:03 Consider a solution initially containing 0.40 mol fluoride anion (F) and 0.30 mol of hydrogen fluoride (HF). If 0.40 mol of HCl are added to this solution, which of the following statements is/are FALSE? Addition of 0.40 mol of HCI will lover the pH of solution by 0.4 unit. O You'll essentially have a weak acid solution situation, with 0.7 mol HF at the end. O You will still have a buffer solution at the end, since you'll still have significant amounts of both weak base and conjugate weak acid. You will no longer have a buffer solution, since all of the buffer capacity was exhausted. The pH will have shifted to a lower pH.

Classify the salts according to strength and role in buffer system. Classifications are as follows: Strong Acid/Conjugate Base, Strong Base/Conjugate Acid, Weak Acid/Conjugate Base, or Weak Base/Conjugate Acid. Example: HCI - Strong Acid/Conjugate Base 1. CaCO3 2. Li2SO3 3. Na₂S 4. Na3PO4 5. KC1 5000000 6. KCN 7. BaClz 8. NSHCO3 9. NACOOCH3 10. N₂HsBr 11. AgNO3 12. KHSO4 13. NaOCI wwwwww 14. NaNO3 15. NaH₂PO4
It was assumed: a) Before any acetic acid was added, essentially all the indicator was in the In- form. b) After the HCl was added, essentially all the indicator was in the HIn form. Justify these assumptions using the measured pH of these solutions and your experimental value for pKHIn to determine: 1) The fraction fo the indicator in the HIn form in solution B before any of solution A was added 2) The fraction of the indicator in the In- form after the HCl was added.
