This page describes how pH changes during various acid-base titrations. The equivalence point of a titration. Sorting out some confusing terms. When you carry out a simple acid-base titration, you use an indicator to tell you when you have the acid and alkali mixed in exactly the right proportions to "neutralise" each other.
25 Αυγ 2024 · The half equivalence point is the stage of the titration at which exactly half the amount of weak base has been neutralised. [NH3 (aq)] = [NH4+ (aq)] At this point it is important to note that the p Kb of the base is equal to the pOH. pKb = pOH at half equivalence.
Accurate Titration Curves: Effortlessly generate detailed titration curves for strong acid and strong base reactions. Visualize the titration process with clear, precise graphs that highlight the equivalence point.
2 Αυγ 2024 · Equivalence point means the point during titration at which the titrant added has completely neutralized the analyte solution. At the equivalence point, the number of moles of titrant added equals the number of moles of an analyte according to the reaction stoichiometry.
14 Αυγ 2020 · The pH at the midpoint, the point halfway on the titration curve to the equivalence point, is equal to the \(pK_a\) of the weak acid or the \(pK_b\) of the weak base. Thus titration methods can be used to determine both the concentration and the \(pK_a\) (or the \(pK_b\)) of a weak acid (or a weak base).
12 Νοε 2023 · In a pH titration you measure the pH as a function of the volume of titrant added and determine the equivalence point as the point in where there is an inflection in the slope of the curve. Figure \(\PageIndex{2}\) shows the four common types of titrations.
