Vedclass · Answer

(B) . The standard reduction potential $(E^{\circ})$ order is $Li $B$. $CsI$ has low solubility in water due to its low lattice energy and hydration enthalpy (statement $B$ is false).$C$. $Li_{2}CO_{3}$ is thermally unstable and decomposes into $Li_{2}O$ and $CO_{2}$ (statement $C$ is false).$D$. Potassium in concentrated liquid ammonia forms a bronze-coloured,diamagnetic solution,whereas dilute solutions are blue and paramagnetic (statement $D$ is false).$E$. All alkali metal hydrides are ionic solids (statement $E$ is true).Note: Based on the standard chemical properties,only statement $E$ is strictly correct. However,if the question implies a specific set,$E$ is the only universally true statement among the choices provided.
