Question
The charge on As2S3 sol is due to the adsorbed :
Options
A.H+
B.OH-
C.O-2
D.S-
Solution
As2S3 colloidal sol is obtained when As2O3 is saturated with H2S :
As2O3 + 3H2S → As2S3 + 3H2O.
As2S3 adsorbs S2- ions (common between H2S and As2S3 and thus is negatively charged).
As2S3 + H2S → As2S3 ; S2- : 2H+.
As2O3 + 3H2S → As2S3 + 3H2O.
As2S3 adsorbs S2- ions (common between H2S and As2S3 and thus is negatively charged).
As2S3 + H2S → As2S3 ; S2- : 2H+.
