WebSo for this problem here where we want 500 mL of a 0.125 M solution of sodium sulfate and start with 1.00 M solution of sodium sulfate, we want to know how much volume of the 1.00 M solution we need to add. So M1 = 1.00 M, M2 = 0.125M, V2= 500 mL, V1= is unknown and what we solve for. So V1 = (0.125 M)(500 mL)/(1.00M) = 62.5 mL.

Webwhy it is or is not. If it is not a chemistry you'd choose for this buffer, please suggest an alternative chemistry and justify your choice. (5 points) Tris is not ideal for a buffer at this pH, as its pKa is more than 2 pH units away from 6.0. Thus, at pH 6.0, Tris would be >90% protonated, and would be a lousy buffer against added acid. http://personal.denison.edu/~kuhlman/courses/biochem/302_Exam1_Q.pdf WebOct 18, 2024 · A buffer cannot be destroyed by adding too much strong base. it can only be destroyed by too much strong acid. B. An effective buffer has a [base]/ [acid] ratio the range of 10 -100. C. An effective buffer has very small absolut concentrations of acid and conjugate base. D. A buffer is most resistant to PH change when [acid] = [conjugate … john c. maxwell libros
