Question

what are stoichiometric defect in ionic crystal

Answer 1

the stoichiometric defects in the ionic crystal are the defects in which the equal no. of cations and anions from the crystal lattice are removed but the ratio of the cations and anions remains the same as the preceding ratio.....these defects results in the maintenance of electrical neutrality of crystal ....due to removal of components of crystal lattice , the density of it decreases as well as the entropy of it increases.....

Answer 2

$\Huge\blue{\textbf{Answer:}}$

$\blue{\textbf{Stoichiometeic defect:}}$

• Stoichiometeic defects are the defects in which cation-anion ratio does not change.

→ Stoichiometeic defects shown by ionic crystals:

• Shottky defect

• Frenkel defect
