Related to this Question What is the pH of a 500 mL solution that is 0.128 M HA after you add 0.300 moles of NaA (the salt form of the conjugate)? pKa = 5.01 Explain how to use your calculator to find the concentration of hydrogen ion in a solution that has a pH of 7.6....
Vopt is the optimal reaction rate achieved when the first protonable group is deprotonated (pKA) and the second group is protonated (pKB), according to the following equation from the reference [148]. v=Vopt⋅(KAKA+[H+])([H+]KB+[H+]). 1.2. Qo-site reaction From our earlier studies...
