🤓 Based on our data, we think this question is relevant for Professor Brown's class at TAMU.
Acetic acid, HC2H3O2, is a weak acid. The following is the equilibrium equation for its reaction with water:
HC2H3O2 (aq) + H2O (l) ⇌ H 3O+ (aq) + C2H3O2-(aq) Ka = 1.8 x 10-5
What is the pOH of a 4.27 M HC 2H3O2 solution?
Note: Assume that the ionization of the acid is small enough in comparison to its starting concentration that the concentration of unionized acid is almost as large at equilibrium as it was originally. This will allow you to avoid having to solve the quadratic formula when doing your ICE table calculation.
