57 Read Section 16.3 Page 7990) table shows the values of lonization constarts for a number of ses at 25 "C Formula K₂ HC₂H₂O₂ 18x 10-5 HCIO, 1.1 x 103 NH₂ HCIO C 2.9 x 104 K 1.76 10 Which buter system is the best choice to create a butter with pH 7.107 HCO₂/KCIO, HC₂H₂O₂/KC₂H₂O, NHANH CH + HCIO/KCIO Part Previous Answers Correct The effective range for a buffering system is one pil unit on either side of p, Therefore, calculate the pK, for each butter system For HC₂H0₂/KC₂H₂O₂ pk-log K --log(1.8 10 4.74 For HC10/KC10₂ pk-1.96 to HCIO/KCIO, pk,-7.54, and to NH/NH.C. pK, 14.00-pk 14.00-4754 9.25 So. HCIO/KCIOs the best choice to create a buffer with pll7.10 because HCO has the pk, value that is close to 7.10 For the best system, calculate the ratio of the masses of the buffer components required to make the be Express your answer to two siguificant figures.
