WebAug 29, 2024 · 3.13: Titrations. A titration is a volumetric technique in which a solution of one reactant (the titrant) is added to a solution of a second reactant (the "analyte") until the equivalence point is reached. The equivalence point is the point at which titrant has been added in exactly the right quantity to react stoichiometrically with the ... WebJul 19, 2024 · Titration Calculations. There are a number of methods to use when determining the pH of a solution in a titration. Click on each step to see more details. …
WebIn the case of titration of weak acid with strong base, pH at the equivalence point is determined by the weak acid salt hydrolysis. That means we have to find pK b of conjugated base and calculate concentration of OH – starting from there, then use pH=14-pOH formula. See pH of weak acids and bases lecture and pH cheat sheet for details of ...

WebSep 22, 2024 · At this point the reaction is completed, and no more \(\ce{NaOH}\) is required. This is called the equivalence point of the titration. In order to know when the equivalence point is reached, an indicator solution called phenolphthalein is added to the vinegar at the beginning of the titration. Phenolphthalein is a pH sensitive organic dye.
WebThe third step in sketching our titration curve is to add two points after the equivalence point. The pH after the equivalence point is fixed by the concentration of excess titrant, NaOH.
