Question

Which of the following is not a property of hydrophilic sols? a)high concentration of dispersed phase can be easily attained b)coagulation is reversible c)viscosity and surface tension are nearly same as that of water d)the charge of the particle depends on the pH value of the medium; it may be positive, negative, or even zero

Answer 1

c) viscosity and surface tension are not same as of water

Answer 2

Hey dear,

● Answer -
C) Viscosity and surface tension are nearly same as that of water

● Explaination -
- Hydrophilic solution forms hydrogen/ionic bonds with water molecules.
- For hydrophilic solution, viscosity is higher than that of dispersion medium.
- For hydrophilic solution, surface tension is lesser than that of dispersion medium.


Hope this helped you.
