$\mathrm{B}\mathrm{i}\mathrm{C}{\mathrm{l}}_3$, being the salt of a strong acid and weak base, undergoes partial hydrolysis under weakly acidic conditions to give a white precipitate of BiOCl, which dissolves in the excess of the acid.
$\mathrm{B}\mathrm{i}\mathrm{C}{\mathrm{l}}_3+3\mathrm{H}\mathrm{O}\mathrm{H}\to \underset{(\mathrm{p}\mathrm{p}\mathrm{t}.)}{\mathrm{B}\mathrm{i}\mathrm{O}\mathrm{C}\mathrm{l}}+2\mathrm{H}\mathrm{C}\mathrm{l}$
$\mathrm{B}\mathrm{i}\mathrm{O}\mathrm{C}\mathrm{l}+2\mathrm{H}\mathrm{C}\mathrm{l}\to \mathrm{B}\mathrm{i}\mathrm{C}{\mathrm{l}}_3+{\mathrm{H}}_2\mathrm{O}$
