Web1. Vinegar is an aqueous solution of acetic acid (abbreviated as HOAc) and typically contains 5% acetic acid by volume, equal to 0.84 M. Knowing the Ka of acetic acid equals 1.58x 10-5, calculate the pH of vinegar. You don't need to consider the activity coefficient. HOAc <> H+ + OAc- Ka... WebIn the reaction, the base takes an H+ ion from the acid and these two electrons are left behind on this oxygen. Adding an H+ to H2O gives the hydronium ion H3O+, and taking away an H+ from H2O gives the hydroxide ion OH-. We can write an equilibrium constant expression for this reaction. tsp ignition https://entertainmentbyhearts.com
