WebJun 24, 2016 · Ksp = x ⋅ x c − x = x2 c −x. Now, as long as the initial concentration of the acetic acid, c, is significantly higher than the Ksp of the acid, you can use the approximation. c − x ≈ c → valid when c >> Ksp −−−−−−−−−−. In this case, the equation becomes. Ksp = x2 c. which gives you. x = √c ⋅ Ksp. Since x ...

Next you will titrate the acid to find what volume of base is needed to neutralize it completely. Then you will make several known mixtures, in which the acid is 1/4 neutralized, 1/2 neutralized, and 3/4 neutralized. From the salt-to-acid ratio and the measured pH for each solution, you will calculate Ka. brian furch footballWebThis buffer calculator provides an easy-to-use tool to calculate buffer molarity and prepare buffer solutions using the formula weight of the reagent and your desired volume (L, mL, or µL) and concentration (M, mM, or nM).
