Question
Chapter 20, Problem 20.53QP
Interpretation Introduction
Interpretation: For the given
Concept Introduction:
Redox reaction:
Oxidation – redox reaction is popularly known as redox reaction.
In this reaction the oxidation number of a participating chemical species changes to another one.
Some common example of redox reaction includes Fire, dissociation of metals, the browning of fruit, and respiration and photosynthesis etc.
Mechanism of redox reaction:
To define the expected mechanism we have to know the group that they are directly belong to the metal as well as bond associated with the metal –ligand .also mention the oxidation state.

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.
