Ka acid dissociation constant
WebbKa for biochemistry is normally called affinity constant and is the opposite of Kd, dissociation constant. Biochemists probably named this constant while inorganic chemists probably named acid dissociation constant. There is a section in Lehninger discussing Ka vs Kd. I would suggest knowing this for the MCAT. WebbThe acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. Strong acids have exceptionally high Ka values. The Ka value is found by looking at …
