WebbH 3 O + concentration given by water is neglected because dissociation of water is much lower compared to the formic acid dissociation. Because H 3 O + concentration is known now, pH value of formic acid solution can be calculated. pH = -log[H 3 O + (aq)] pH = … WebbLet’s say we need 1L of 10% MeOH with 90% MeCN, 1% Formic Acid and 0.1% AmFm. The mixture will consist of 890 mL of MeCN, 100 mL of MeOH, and 10 mL of buffer solution. … can activia make you sick
