Question

g Suppose you are titrating an acid of unknown concentration with a standardized base. At the beginning of the titration, you read the base titrant volume as 1.84 mL. After running the titration and reaching the endpoint, you read the base titrant volume as 27.30 mL. What volume, in mL, of base was required for the titration?

    Answer:

    25.46 mL

    Explanation:

    In a titration we use the volume and concentration of a solution to determine the previously unknown concentration of other solution. Let’s consider the titration of an acid of unknown concentration with a standardized base (a base whose concentration we know). The generic neutralization reaction is:

    HA + BOH ⇒ BA + H₂O

    The base is in the buret and we will add it to the acid until the equivalence point is reached. The volume of base used is equal to the difference between the final reading of the buret and the initial reading of the buret.

    V = 27.30 mL – 1.84 mL = 25.46 mL
