If 1.0 L of a .25 M acetic acid solution has a pH of 2.67, what is the pH after adding .10 mol of sodium acetate? How does sodium acetate dissociate?
|
The pH is 4.35 and without the added common ion the pH would be 2.68.
- The equil. will shift far less to the right and more to the left - so x= [H3O+] is less than .0021 M in the prescence of added acetate ion. - Na + is not considered in the pH and the Acetate is the common ion and is a part of the reaction... CH3CO2H + H2O yields H3O+ + CH3CO2- |
