Statement I: In any ionic solid (MX) with Schottky defects, the number of positive and negative ions — Solid State Chemistry Question
Question
Statement I: In any ionic solid (MX) with Schottky defects, the number of positive and negative ions are same. Statement II: Equal numbers of cation and anion vacancies are present.
Answer: A
💡 Solution & Explanation
Statement I is correct: electrical neutrality is maintained in crystals with Schottky defects, so the overall ratio of cations and anions remains equal to the stoichiometry of MX. Statement II is correct: equal numbers of cation and anion vacancies are formed, which is the direct explanation of Statement I.
