Question

Part 3: Consider the following situation in the equivalent weight determination of an organic acid: the student performed the titration using the impure acid by mistake (the impurity is not reacting with NaOH). Would the equivalent weight calculated from the data be HIGHER or LOWER than the real value? Circle the right answer. (Show Your Work)

Answer 1

since the aced is impure, the and the impurity is not reacting with Noon, which means it will not be used in calculation of equivalent weight So, since amount of acid is more ( impureity of pure acid) amount of NaOH used is less. So, the value which is estimated will be resser than that of actual value. csscanned with CamScanner
