WebThe results of an acid–base titration can be summarized using a titration curve, which plots pH vs. volume of titrant added. For the titration of a strong acid with a strong base, the curve begins acidic and then turns basic after the equivalence point, which occurs at pH = 7. WebIn a weak base-strong acid titration, the acid and base will react to form an acidic solution. A conjugate acid will be produced during the titration, which then reacts with water to form hydronium ions. This results in a solution with a pH lower than 7. florida hotel owners liability

If the acid dissociation constant(pKa) of the acid or base dissociation constant (pKb) of base in the analytesolution is known, its solution concentration (molarity) can be determined. great wall orange chickenWebMar 9, 2024 · K_a = 2.1 * 10^(-6) The idea here is that at the half equivalence point, the "pH" of the solution will be equal to the "p"K_a of the weak acid. Assuming that you're titrating a weak monoprotic acid "HA" with a strong base that I'll represent as "OH"^(-), you know that at the equivalence point, the strong base will completely neutralize the weak acid. great wall ouedkniss

"WebIn this particular instance, this would also be the neutral point of the titration, because sodium chloride solution has a pH of 7. But that isn't necessarily true of all the salts you might get formed. For example, if you titrate ammonia solution with hydrochloric acid, you would get ammonium chloride formed.
