Consider the following reactions of 1A metals.

M + $\left(x+y\right)N{H}_3$ $\stackrel{}{\to }{\left[M{\left(N{H}_3\right)}_x\right]}^{+}+{\left[e{\left(N{H}_3\right)}_y\right]}^{-}$  

$M_{\left(am\right)}^{+}+e^{-}+N{H}_3\left(\mathcal{l}\right)\stackrel{}{\to }MN{H}_{2\left(am\right)}+\frac{1}{2}{H}_2\left(g\right)$

Which of the following statement is

INCORRECT?

Li⁺ has the highest hydration enthalpy.

Hence it is most hydrated

Therefore, Correct order of hydrated radii is Cs⁺ < Rb⁺ < K⁺ < Na⁺ < Li⁺

Sodium carbonate is a white crystalline solid which exists as a decahydrate,  This is also called washing soda.

Suspension of slaked lime in water is known as milk of lime

Crude sodium chloride obtained by crystallisation of brine solution contains CaSO₄, Na₂SO₄ and MgCl₂

Beryllium salts are easily hydrolysed

Gypsum : CaSO₄ * 2H₂O
