The disperse phase, dispersion medium and nature of colloidal solution (lyophilic or lyophobic) of 'gold sol' respectively are :
- A solid, solid, lyophobic
- B liquid, liquid, lyophobic
- C solid, liquid, lyophobic
- D solid, liquid, lyophilic
Answer & Solution
Correct Answer
(C) solid, liquid, lyophobic
Step-by-step Solution
Detailed explanation
Colloidal solution of gold is obtained when dispersed phase is solid and dispersion medium is liquid. Substances like metals cannot be brought into the colloidal state simply by bringing them in contact with water and therefore, special methods are devised for the purpose.…
