Finding concentration from ka
WebKa from pH We can use pH to determine the Ka value. pH is a standard used to measure the hydrogen ion concentration. pH = – log [H + ] We can rewrite it as, [H +] = 10 -pH. If … WebQuestion: [1] A group of Aggie spudents prepared vibegar in the lab by using an initial concentration of Acetic acid of 0.25M. The dissociation of the acetic acid is shown below. If the Ka of the acetic acid was 4.8×10−4, calculate the equilibrium concentration of [CH3COOH3] [H3O+]. [CH3COO∘]. pH and [OH2] of the vinegar.
