Question

(A) The basic character of lanthanoid hydroxides,$Ln(OH)_3$,decreases as the ionic radius of the lanthanoid ion decreases due to lanthanoid contractio

Vedclass · Accepted Answer

Less than $Ca(OH)_2$ but more than $Al(OH)_3$

Vedclass · Answer

(A) The basic character of lanthanoid hydroxides,$Ln(OH)_3$,decreases as the ionic radius of the lanthanoid ion decreases due to lanthanoid contraction.Lanthanoid hydroxides are less basic than alkaline earth metal hydroxides like $Ca(OH)_2$ but are more basic than $Al(OH)_3$,which is amphoteric.Therefore,the basicity follows the order: $Ca(OH)_2 > Ln(OH)_3 > Al(OH)_3$.
