`As_2S_3` sol has a negative charge. Capacity to precipitate it is highest in

A

`AlCl_(3)`

B

`Na_(3)PO_(4)`

C

`CaCl_(2)`

D

`K_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Negatively charged `As_(2)S_(3)` sol coaulated most effectively by `AlCl_(3)`. This is because oppositely charged `Al^(+++)` ions have maximum charge.
`As^(3+) gt Ca^(2+) gt Na^(+)`.

As_2S_3 sol is a

Metal sol is negatively charged.

In a colloidal state, the particle size of he dispersed phase ranges between 10^(3) to 10^(6) pm and the colloidal sol is of heterogeneous nature. Depending upon the ease with which these sols are formed, the colloidal sols are cassified as lyophilic and lyophobic. THe stability of a colloidal sol is due to the presence of charge on the sol particles and the neutralisation of the same is known as coagulation or precipitation. The coagulationg power of the active ions of he electrolytes can be compared with the help of Hardy-Schulze Law. The protecting power of the lyophilic sols can be compared with the help of gold number. Lesser the value of gold number, more will be the protecting power of the lyophilic sol. The areseneous sulphide sol has negative (-) charge. The maximum power to precipitate it is of :
