Vedclass · Answer

(A) Statement $(i)$ is correct: In $CuSO_4 \cdot 5H_2O$, four water molecules are coordinated to the $Cu^{2+}$ ion, and one water molecule is hydrogen-bonded to the sulphate ion.Statement $(ii)$ is correct: Lanthanum and zirconium form non-stoichiometric (interstitial) hydrides, such as $LaH_{2.87}$ and $ZrH_{1.9}$.Statement $(iii)$ is incorrect: In the solid form of $H_2O$ (ice), each oxygen atom is surrounded by four other oxygen atoms in a tetrahedral arrangement at a distance of $276 \ pm$, not octahedral.Therefore, statements $(i)$ and $(ii)$ are correct.
