Web(1.00 M CH3COOH)(200.0 mL)(1 L/1000 mL) = 0.200 mol CH3COOH (10.0 g NaCH3COO)(1 mol/82.03 g) = 0.122 mol NaCH3COO Substitute these values, along with the Kavalue, into the above equation and solve for the hydronium ion concentration. Convert the hydronium ion concentration into pH. [H3O+] = (1.7 x 10-5)(0.200/0.122) = 2.79 x 10-5 pH = 4.56 WebHowever, you have to be aware of your buffer's pH. If you took a reaction of a weak acid that has a small Ka value, it will only produce some conjugate base and it's pH might be very low, like a 2.
