Document Summary

Chem6c chapter 21 notes: bufers and the titraion of acids and bases. Ha + h2o h3o+ + a- A- + h2o oh- + ha. If both ka and kb are small, then [ha] [ha]0 and [a-] [a-]0: h-h equaion: ph pka + log[base]0/[acid]0. Value of ka for conjugate acid-base pair between 10-4 and 10-11. Raio [base]0/[acid]0 must be between 0. 1 and 10. Values of [base]0 and [acid]0 between 10-3 and 1. Use the h-h equaion and subsitute the values given in the problem (ph, pka) Solve for the raio of base to acid. Subsitute x as the number of ml of the molar base and y as the number of ml of the molar acid. Create another equaion in which x + y = the desired amount of soluion (in ml) Subsitute and solve for x and y, to give the amount of x (base) and y (acid) you want to mix.
