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.
Which one of the following is correctly matched?
The coagulation values in millimoles per litre of the electrolytes used for the coagulation of As2S3 are given below
(I) (NaCl) = 52
(II) (BaCl2) = 0.69
(III) (MgSO4) = 0.22
The correct order of their coagulating power is:
On which of the following properties does the coagulating power of an ion depend?
What happens when a colloidal sol of Fe(OH)3 and As2S3 are mixed?
Why are lyophillic colloidal sols are more stable than lyophobic colloidal sol?
Which one of them is not a surfactant?
Which one of the is not a surfactant?
Which one of the is not a surfactant?
