Statement I: Due to Frenkel defect, there is no effect on the density of the crystalline solid. Stat — Solid State Chemistry Question

💡 Solution & Explanation

Statement I is correct: the density of a crystal is unaffected by Frenkel defects. Statement II is correct: in a Frenkel defect, an ion is simply dislocated from its normal lattice site to an interstitial site within the crystal, meaning no mass is lost, which explains why the density remains unchanged.
