Weak Acid (HA) titrated with NaOH + PLOT

WebIn strong acid-weak base titrations, the pH at the equivalence point is not 7 but below it. This is due to the production of a conjugate acid during the titration; it will react with water to produce hydronium (H 3 O +) ions. In the example of the titration of HCl into ammonia solution, the conjugate acid formed (NH 4+) reacts as follows: WebSo, if we plug in our pOH into here, pH is equal to 14.00 minus 5.33, which is 8.67. So, we're at the equivalence point, but this is a titration of a weak acid with a strong base. And so, we have a basic salt solution at the equivalence point. So, our pH is in the basic range. how is simd worked outWebTitration of a Weak Acid with a Strong Base Consider the titration of 25.00 mL of 0.100 M CH 3 CO 2 H with 0.100 M NaOH.
