Acid-base titrations are an experimental approach to determine the concentration of an unknown acid or base (0:56). Your episode starts by introducing the terms analyte and titrant (1:49) and looks at two examples: In the first example, we are titrating a strong acid with a strong base (2:03). We describe the shape of the titration curve (2:14) and define equivalence point (2:44), the point at which the number of moles of titrant and number of moles of analyte are the same. Using the equivalence point, we can calculate the molarity of the unknown analyte (3:03). The second example outlines the titration of a weak acid with a strong base (4:26) and describes why the equivalence point is at a pH higher than 7 (5:19). It also discusses the half-equivalence point (6:00), which can be used to determine the pKa of the weak acid.Question: How many equivalence points will the titration curve of a diprotic acid show?Thank you for listening to The APsolute RecAP: Chemistry Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.
