Question
Chapter 11, Problem 17QP
Interpretation Introduction
Interpretation:
The type of forces that are broken when a nonpolar substance dissolves in a nonpolar solvent, and the new type of forces formed are to be determined.
Concept Introduction:
Nonpolar solutes dissolve in a nonpolar solvent but not in polar solvents because there are no strong intermolecular forces between the solute and solvent molecules, if nonpolar solute is dissolved in a polar solvent.

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.
