Identify the correct statements about alkali metals
(A) The order of standard reduction potential \(\left( M ^{+} \mid M \right)\) for alkali metal ions is \(Na > Rb > Li\).
(B) LiI is highly soluble in water.
(C) Lithium carbonate is highly stable to heat.
(D) Potassium dissolved in concentrated liquid ammonia is blue in colour and paramagnetic.
(E) All the alkali metal hydrides are ionic solids.
Choose the correct answer from the options given below
[JEE Main 2023, 24 Jan (Shift 2)]
(A), (B) and (E) only
\(Na > Cs > Li -\) true \(\{\) If considered with sign \(\}\)
CsI is less soluble in water due to smaller hydration enthalpy of it's two ions
\(Li _2 CO _3\) is not so stable to heat and gets converted into \(Li _2 O\) and \(CO _2\).
Potassium dissolved in liquid ammonia give deep blue solutions that are paramagnetic but in the concentrated solution, the blue. All the alkali metal hydrides are ionic solid (True).
