Question
Chapter 6, Problem 23Q
Interpretation Introduction
Interpretation:
Whether the given diagram represents p-type silicon semiconductor or n-type silicon semiconductor has to be explained.
Concept Introduction:
n-type semiconductor:
In this type of semiconductors, conductivity is increased by doping an element with 5 valence electrons (i.e. doped atom acts as a donor impurity).
p-type semiconductor:
In this type of semiconductors, conductivity is increased by doping an element with 3 valence electrons (i.e. doped atom acts as an acceptor impurity).

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.
