What is the equilibrium constant of CH3COOH?
When placed in water, weak acids (generic
In the case of acetic acid, which is a weak acid, the equilibrium can be described like this:
The equilibrium constant is
Since the concentration of liquid water is left out of the expression, the equilibrium constant for this reaction is called acid dissociation constant,
The values of the acid dissociation constants for various acids are usually given to you in an exam, acetic acid's equilibrium constant being
