red between the fluorine atoms. b. Only 4 valence electrons will travel around each fluorine atom. c. Twelve valence electrons will travel around each fluorine atom, but only 2 will remain around the respective atoms. d.

Hello!
The chemical reaction for the dissociation of Acetic Acid is the following:
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺
To solve the problem we are going to use the Henderson-Hasselbach Equation, as follows, but first we need to know the pKa:
![pH=pKa + log( \frac{[CH_3COO^{-} ]}{[CH_3COOH]} )](https://tex.z-dn.net/?f=pH%3DpKa%20%2B%20log%28%20%5Cfrac%7B%5BCH_3COO%5E%7B-%7D%20%5D%7D%7B%5BCH_3COOH%5D%7D%20%29)
So, the pH of this solution is 5,24
Have a nice day!
