The coagulation power of an electrolyte ...

The coagulation power of an electrolyte for `As_(2) S_(3)` decreases in the order:

A

`Na^(+) gt Al^(3+) gt Ba^(2+)`

B

`PO_4^(3-) gt SO_4^(2-) gt Cl^(-)`

C

`Cl^(-) gt SO_4^(2-) gt PO_4^(3-)`

D

`Al^(3+) gt Ba^(2+) gt Na^(+)`

Text Solution

Verified by Experts

`As_2S_3` is a negative sol and therefore coagulating power decreases as `Al^(3+) gt Ba^(2+) gt Na^(+)`

coagultion is the process by which the dispersed phase of a colloid is made to aggregate and thereby separtate from the continuous phase. The minimum concetration of an eletrolyte in milli-moles per litre of the electrolyte solution which required to cause the caogultion of colloidal sol is called coagution value . therefroe higher is the coagulatings power of effective ion, smaller will be the coagultion value of the electrolyte. As_(2)S_(3) sol si negatively charged. Capacity to perciopitate of a given colloid depends upon :
