Which one of the following statements

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

  1. Their viscosity is of the order of that of $\mathrm{H}_{2} \mathrm{O}$.

  2. The sols cannot be easily coagulated.

  3. They do not require electrolytes for stability.

  4. These sols are reversible in nature.

Correct Option: 1


$\rightarrow$ Viscosity of hydrophilic sol $>$ viscosity of $\mathrm{H}_{2} \mathrm{O}$

$\rightarrow$ Hydrophilic sol is more stable so can’t be easily coagulated.

$\rightarrow$ Hydrophilic sols are reversible sols.

$\rightarrow$ No electrolytes are required to stabilise hydrophilic sol.
