Ph of a weak acid strong base titration
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: WebFor the titration of a weak acid with a strong base, the pH curve is initially acidic and has a basic equivalence point (pH is greater than 7). The section o...

WebA weak acid will react with a strong base to form a basic (pH > 7) solution. When a weak acid reacts with a weak base, the equivalence point solution will be basic if the base is … WebAn acid-base titration can be monitored either through the use of an acid-base indicator or through the use of a pH meter. Monitoring the pH during titration of a weak acid with a strong base leads to a titration curve, Figure 1. The equivalence point occurs when enough base has been added to react completely with all of the weak acid ...

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. sharks rugby team logo
