Which one of the following statements is FALSE for hydrophilic sols?

Which one of the following statements is FALSE for hydrophilic sols?

Options

  1. AThese sols are reversible in nature.
  2. BTheir viscosity is of the order of that of H2O{H}_{2}O.
  3. CThe sols cannot be easily coagulated.
  4. DThey do not require electrolytes for stability.

Correct answer

B. Their viscosity is of the order of that of H2O{H}_{2}O.

Step-by-step solution

Viscosity of hydrophilic sol >>viscosity of H2O{H}_{2}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.
