Which from following statements is NOT true about lyophilic colloids?
Options
- AThe particles of dispersed phase have greater affinity for the dispersion medium.
- BThese are reversible.
- CThese are self stabilized.
- DCoagulation occurs even by adding very small amount of electrolytes.
Correct answer
D. Coagulation occurs even by adding very small amount of electrolytes.
Step-by-step solution
In lyophilic colloids, the particles of dispersed phase have a great affinity for the dispersion medium. They are reversible and self-stabilized colloids. Addition of large amount of electrolytes causes precipitation or coagulation of lyophilic sols.
