Which one of the following statements is FALSE for hydrophilic sols ?
Select the correct option:
A
Their viscosity is of the order of that of H2O.
B
The sols cannot be easily coagulated.
C
They do not require electrolytes for stability.
D
These sols are reversible in nature.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
→ Viscosity of hydrophilic sol $>$ viscosity of $\mathrm{H}_2 \mathrm{O}$
→ Hydrophilic sol is more stable so can't be easily coagulated.
→ Hydrophilic sols are reversible sols.
→ No electrolytes are required to stabilise hydrophilic sol.
