Question
Chapter 31, Problem 31.66P
Interpretation Introduction
Interpretation:
The meaning of indiscriminate application of antibiotics should be explained.
Concept Introduction:
Antibiotics refer to the components obtained from microbes to eradicate other microorganisms. For example, streptomycin and penicillin are antibiotics, and these are used in the treatment of various kinds of bacterial infections. One usual demerit of antibiotics application is that the individuals seem to develop certain kinds of allergies.

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
