What Is The Relationship Between Ph And Pka

The pH of a buffer is determined by two factors; 1) The equilibrium constant Ka of the weak acid and 2) the ratio of weak base [A-] to weak acid [HA] in solution. 1) Different weak acids have different equilibrium constants (Ka). Ka tells us what proportion of HA will be dissociated into H+ and A- in solution.

Sep 11, 2014  · Hi guys, in this video I have tried to explain the relation between pH and pKa in connection with amino acids. If you have any questions feel free to ask.

3) Describe the relationship between the buffer working range and pK values • Buffer solutions work best when their pH levels are near the pKa of acid. In order to oppose charge, the pH of a solution needs to be + 1. Ka is the acid dissociation constant and pKa =.

pH is the negative logarithm of [H+], -Log[H+]. pOH is -Log[OH-]. Pure water H2O ionizes very slightly to H+ and OH-. In pure water, [H+] = 1 x10^-7, and [OH-] = 1 x 10^-7.

Whats the relationship between the two? If a pH is above 7= basic If below 7= acidic What about for pka then? I am so confused! I know how to calculate Pka & pH.
