1) A buffer contains 0.15 mol of propionic acid (C2H5COOH) and 0.10 mol of sodium propionate (C2H5COONa) in 1.20L. (a) What is the pH of this buffer? (b) What is the pH of the buffer after the addition of 0.01 mol of NaOH? (Ka for C2H5COOH is 1.3*10-5) 2) Using the value of Ksp for Ag2S (see Appendix D), Ka1 and Ka2 for H2S (see Appendix D), and Kf = 1.1*105 for AgCl2-, calculate the equilibrium constant for the following...
