1. Determine the volume, in mL, of 2.00 M HC2H3O2 stock solution that would need to be diluted to 50 mL in order to produce a solution that is 0.30 M in HC2H3O2.
2. Write the equilibrium constant expression, Ka, for the ionization of acetic acid, HC2H3O2.
3.In the rICE table for the dissociation of acetic acid, what is the expression for acetic acid taken directly from the equilibrium line of your ICE table? Do not use the x is small assumption. [HAc]i is the initial concentration of acetic acid
Ox – [HAC); O not included in the rICE table because it is a (s) or (I) O [HAc); -x O [HAC); Ох
o ka [HAC] [H20] [H+] [Ac-] [HAC] [H+] [Ac-] o ka = [H+] [Ac-] [HAC] [H20] ka = [H+] [Ac-] [HAC]
