1. Using the equation pKa= -log Ka, calculate the Ka from the pH value and the starting acetic acid concentration.
2. Calculate the Ka of acetic acid.
** Please see the attached file for the complete solution response **
There are many weak acids, which do not completely dissociate in an aqueous solution. As a general discussion of weak acids, let HA represent a typical weak acid. Then its ionization can be written as:
HA = H+ + A-
In a solution whose label concentration is C (= [HA] + [A-]), let us assume that x is the concentration that has ...
This solution provides step-by-step calculations for Ka.
