WebOur goal is to calculate the pH of this buffer solution represented in the particulate diagram. And so first, we need to know the pKa of the weak acid, which is acetic acid. At 25 degrees Celsius, the Ka value for acetic acid is equal to 1.8 times 10 to the negative fifth. The Ka value is less than one because acetic acid is a weak acid. WebKa is 10^-7 because once you calculate -log(Ka) you get pH=7, which is neutral water. The same goes for Kb (also 10^-7). You can do the same log calculation but solve for pOH=7
