As2O3(aq)+3H2S(aq) xrightarrow[] underset beginsmallmatrix Colloidal sol endsmallmatrix mathopAs2S3 +3H2O AS2S3 then adsorbs S2- ions from H2S solution containing H+ and S2- ions and becomes negatively charged.

Q. arsenic sulphide sol is prepared by passing $H_{2} S$ through arsenic oxide solution. The charge developed on the particles is due to absorption of

$H^{+}$

$S^{2 -}$

$O H^{-}$

$O^{2 -}$

$A s_{2} O_{3} (a q) + 3 H_{2} S (a q) C o ll o i d a l so l A s_{2} S_{3} + 3 H_{2} O$ $A S_{2} S_{3}$ then adsorbs $S^{2 -}$ ions from $H_{2} S$ solution containing $H^{+}$ and $S^{2 -}$ ions and becomes negatively charged.
