Question

15. Associated colloids :
(a) raise both the surface tension and viscosity of water
(b) lower both the surface tension and viscosity of water
(ç) lower the surface tension and raise the viscosity of water
(d) have greater concentration at the surface layer than the bulk of the solution​

Answer 1

Ans C

Associated colloids are those colloids which behave as normal strong electrolytes at low concentrations but exhibit colloidal properties at higher concentrations due to the formation of aggregated particles. The aggregated particles thus formed are called micelles.
