NEETChemistrySolid State
Explain how vacancies are introduced in an ionic solid when a cation of higher valence is added as an impurity in it.
Options
- AThe higher valence cation occupies a tetrahedral void, creating an anionic vacancy.
- BThe higher valence cation occupies an octahedral void, creating a cationic vacancy.
- CThe higher valence cation replaces a lower valence cation in the lattice, creating cationic vacancies.
- DThe higher valence cation replaces an anion in the lattice, creating anionic vacancies.
Correct answer
C. The higher valence cation replaces a lower valence cation in the lattice, creating cationic vacancies.
Step-by-step solution
Correct Option is : (C) The higher valence cation replaces a lower valence cation in the lattice, creating cationic vacancies.
