How do we know which acid is stronger and which is weaker? By identifying theacidand theconjugate acid, andcomparing their two pKavalues! Acid base reactions will favor formation of the acid with the higher pKavalue. It’s not completely unlike how areas of high pressure will flow to areas...
Plug your values into the Henderson-Hasselbalch equation, pH = pKa + log ([A-]/[HA]), where [A-] is the concentration of conjugate base and [HA] is the concentration of the conjugate acid. Keep in mind that since you've measured pH as a function of the titrant's volume, you need...

Theoretical considerations and accessible experimental data were used to understand how the pK a values of pharmaceutically relevant buffers depend on these factors. Changes in temperature also affect the buffer pK a . Carboxylic acid moieties were least affected by changes in temperature. Buffers ...

pKa of Acids & Functional Groups | Overview & Examples from Chapter 13 / Lesson 7 41K Explore the concepts of pKa and pH values and how they relate to acids and bases. Learn the trends in pKa value for functional groups, acids, and bases with examples. Related...
Ka values can be easily looked up online, and you can find the pKa using the same operation as for pH if it is not listed as well.Online pH and pOH calculator See the Resources for a web tool that allows you to determine the pH of various acidic and basic solutions. You can use ...
For the acid H_2A, the values of k_{a1} = 4.6 times 10^{-5} and K_{a2} = 6.4 times 10^{-7}. What is the acid dissociation constant for: H_2A + H_2O to 2H_3O^+ + A^{2-} What is the relationship of the successive equivalence point vol...
So, what’s a method development chemist to do? Know the logP and pKa of your analytes of interest. Use the most nonpolar solvent you can. Try combinations of hexane and ethyl acetate and choose the lowest amount of ethyl acetate that provides the desired recovery. Modify DCM with 5-10%...
