The possible oxidation state of $Tl$ are
$+1$ and $+2$
$+2$ and $+3$
$+1$ and $-1$
$+1$ and $+3$
White fumes appear around the bottle of anhydrous aluminium chloride. Give reason.
When $AlCl_3·6H_2O$ is strongly heated, then it forms
In $IIIA$ group, $Tl$ (thalium) shows $+1$ oxidation state while other members show $+3$ oxidation state. Why
The function of fluorspar in the electrolytic reduction of alumina dissolved in fused cryolite $(Na_3AlF_6)$ is :
An aqueous solution of borax is
