A 24.0 mL sample of 0.115 M sulfurous acid (H,S03) is titrated with 0.1019 M KOH At what added volume of base solution does the first equivalence point occur? Express your answer in mililiters to three significant figures. V. mL Submit Request Answer Vorue nertlel

Learning Goal: To calculate the pH at the equivalence point for various types of titrations. The equivalence point in an acid-base titration is the point at which stoichiometrically equivalent quantities of acid and base have been mixed together. At this point the reaction is complete because all analyte has been consumed by titrant. On a titration curve, the equivalence point is represented by the point of inflection (where the curve changes concavity). The figure (Figure 1) shows the titration of 40.0 mL of 0.100 M HCl with 0.100 M NaOH. When 40.0 mL of the NaOH solution is added, the acid-base neutralization reaction is complete. When analyzing titrations involving weak acids or bases, consider how the neutralization reaction will impact the pH of the system. For example, when titrating a weak acid with a strong base, at the equivalence point all the base has been used to neutralize the acid forming its conjugate weak base Figure E 14 12 10 8 6 4 2 0 0 Equivalence point 20.0 40.0 mL…
