Known ka of acetic acid
WebLet’s assume our analyte is acetic acid CH 3 _{3} 3 ... In an acid-base titration, a known volume of either the acid or the base (of unknown concentration) is placed in a conical flask. The second reagent (of known concentration) is placed in a burette. ... it depends on the … WebIt is less compared to, say, ammonia, which is a known weak base. ... but you can find the Ka for acetic acid. So, acetic acid and acetate is a conjugate acid-base pair, and the Ka value for acetic acid is easily found in most text books, and the Ka value is equal to 1.8 x 10-5. And our goal is to find the Kb.
