WebTitration curves for weak acid v weak base The common example of this would be ethanoic acid and ammonia. It so happens that these two are both about equally weak - in that case, the equivalence point is approximately pH 7. Running acid into the alkali This is really just a combination of graphs you have already seen. WebIn a strong acid-strong base titration, the acid and base will react to form a neutral solution. At the equivalence point of the reaction, hydronium (H+) and hydroxide (OH-) ions will react to form water, leading to a pH of 7. This is true of all strong acid-strong base titrations. WebWhat is interesting, and different from the strong acid-base titrations, is that the pH at the equivalence point is not 7. It is 8.75, and this is because of the accumulated acetate ion which is formed as the acetic acid reacts with NaOH. It is a salt of a weak acid, and a strong base, therefore, it increases the pH. csc minneapolis m health
