If it contains CH3COONa, that acts as a pseudo buffer but it isn't a real buffer. A real buffer would also contain acetic acid, CH3COOH. The pH of a 1 mol/dm^3 sodium acetate solution has a pH of.........
.........CH3COO^- + HOH ==> CH3COOH + OH^-
I..............1 M.................................0...................0
C............-x.....................................x....................x
E...........1-x.....................................x...................x
Kb for CH3COO^- = (Kw/Ka) for CH3COOH) = (x)(x)/(1-x)
Solve for x = (OH^-) and convert to pH. Post your work if you get stuck.
Calculate the pH of a buffer solution containing 1.0 mol/dm3 CH3COONa.
I need a step by step solution and explanation. thank you
