Vedclass · Answer

(C) The most common and stable oxidation state for lanthanoid elements $(Ln)$ is $+3$. Therefore,when a lanthanoid reacts with the hydroxide ion $(OH^-)$,it forms a compound where the charge is balanced. Since the hydroxide ion has a charge of $-1$,three hydroxide ions are required to balance the $+3$ charge of the $Ln^{3+}$ ion. Thus,the general formula for lanthanoid hydroxide is $Ln(OH)_3$.

If $Ln$ represents a lanthanoid element,find the general formula of lanthanoid hydroxide.
