Current Attempt in Progress One of the most common buffers used in protein chemistry is a weak base called TRIS (the nitrogen atom of the amino group is the basic portion of the molecule): HO. Z eTextbook and Media HO -NH₂ HOCH,CNH, TRIS OH A biochemist prepares a buffer solution by adding enough TRIS and 12 M HCI to give 1.0L of a buffer solution that has concentrations [TRIS] 0.28 M and [TRISH] -0.65 M. (pK, of TRIS is 5.91.) (a) Calculate the pH of the buffer solution. pH- (b) Suppose that 6.6 mL of 12 M HCl is added to 12 L of the buffer solution; calculate the new pH of the solution. pH-
We want to prepare a buffered solution having a pH of 3.33 using concentrated (23.6 M) formic acid (HCOOH) and solid sodium formate (HCOONa). K, for formic acid is 1.8 x 10. Calculate the ratio [HCOO (aq)]/[HCOOH(aq)] in the buffered solution required to achieve a pH of 3.33. [HCOO {agl]/[HCOOH(ag) eTextbook and Media Hint Save for Later Attempts: 0 of 3 used Hint Submit Answer If the total molarity of formic acid plus formate ion in the buffered solution is 0.200 M, calculate the volume of concentrated acid and mass of sodium formate that must be dissolved in 1.00 L of water. mL formic acid g sodium formate
