When starting with completely un-dissociated acetic acid, is it accurate to assume that [HOAc]0 = [HOAc]eq? Why or why not? 2) A highly concentrated acetic acid solution contains 15.0 M acetic acid at equilibrium. What are the equilibrium concentrations of the hydronium and acetate ions in this solution?

Question

1) When starting with completely un-dissociated acetic acid, is it accurate to assume that [HOAc]0 = [HOAc]eq? Why or why not?

2) A highly concentrated acetic acid solution contains 15.0 M acetic acid at equilibrium. What are the equilibrium concentrations of the hydronium and acetate ions in this solution? 

HOAC (ag) + H,O (1) = H3O† (aq) + OAC¯ (aq)
OAc is an abbreviation for the acetate ion, CH3COO", and H3o* is the hydronium ion (lone
protons, H* (aq), do not exist!).
