What happens when a colloidal sol of Fe(OH)3 and As2S3 are mixed?
Advertisements
उत्तर
On mixing Fe(OH)3 positive sol and As2S3 negative sol, mutual coagulation occurs which causes precipitation. When these sol got mixed with each other, due to Fe3+ and S2− ions neutralisation of charges will happen and precipitate will be formed.
\[\ce{Fe(OH)3 + As2S3 -> Fe2S3 + As(OH)3}\]

Fog is colloidal solution of ____________.
Assertion: Coagulation power of Al3+ is more than Na+.
Reason: greater the valency of the flocculating ion added, greater is its power to cause precipitation.
