1. The problem statement, all variables and given/known data What concentration of ethanoate (acetate) ions is expected in a 0.18 mol/L solution of ethanoic (acetic) acid? Ka is 1.76 x 10-5 at 25°C. 2. Relevant equations Ka=products/reactants 3. The attempt at a solution I know that Ka=1.76 x 10-5=products/reactants but I really don't know what to do from there. I have tried the ICE box method; initial, change, equilibrium but that doesn't seem to work. My textbook only covers the ICE box method and the basic formula, help is appreciated!
