A chemist dissolves 75 g of acetic acid in enough water to prepare two litres of solution. a) What is the concentration of H3O+ ions? b) What is the concentration of the acetate ion (the conjugate base)?c) What is the pOH of the solution?  Ka of acetic acid = 1.8 x 10-5 You may use the desmos online calculator M = mol/L                                           mass = moles x molar mass pH = -log[H+]                                                 [H+] = 10-pH pOH = -log[OH-]                                                 [OH-] = 10-pOH
