WebbVideo transcript. - Here we have a titration curve for the titration of 50 milliliters of 0.200 molar of acetic acid, and to our acetic solution we're adding some 0.0500 molar sodium hydroxide. So once again we're putting pH in the Y axis, and down here in the X axis is the milliliters of base that we are adding. WebbThe pKa represents the pH level. It makes it easier to see the H + concentration. pKa = -log[Ka], just as pH = -log[H +] or -log[H 3 O +], is calculated using a similar formula: pKa = -log[Ka]. The acid dissociation constant, Ka, simply indicates how much dissociation that particular acid will experience on the product or reaction side.
