Now, for a complete equilibrium problem
Consider the following general reaction:
HC2H3O2 (aq) + H2O (l) ⇌ H3O+ (aq) + C2H3O2–(aq) Kc = 1.8 x 10–5 (at 25 ºC)
If a solution initially contains (7.9x10^-1) M of HC2H3O2, (and no H3O+ or C2H3O2– ), what is the equilibrium concentration of H3O+ (aq) in the mixture?
In the appropriate blanks, provide the equilibrium [H3O+ (aq)], in the solution, in M, to two significant figures and to the appropriate power
