So we have only the concentration of acetate to worry about here. This is something you learn with experience, although it helps if you can remember the names of the common strong acids (HCl, HBr, Hi, H2SO4, HNO3, HClO4) and strong bases (hydroxides of Group 1 and 2 elements). There's a very good chance that if you have an acid or base that is not on this list, then it is a weak acid or base - this is particularly the case if it contains carbon (eg, CH3COOH). The amount of acid and base conjugates in the buffer are twice the amount of added acid.) Molecules can have a pH at which they are free of a negative charge. (All hydrogen halides are strong acids, except for HF). And if you take a proton away from water, if you take an H+ away from H2O, you get OH-, or the hydroxide ion. Explain.
