Which of the following process is not responsible for the presence of electric charge on the sol particles?
1 Absorption of ionic species from solution
2 Formation of Helmholtz electric double layer
3 Adsorption of ionic species from solution
4 Electron capture by sol particles
Explanation:
Absorption of ionic species from solution is not responsible for the presence of electric charge on the sol particles. Charge on the sol particles is due to (i) Electrons capture by sol particles during electro dispersion of metal. (ii) Preferential adsorption of ionic species from solution. (iii) Formation of Helmholtz electrical double layer.

A freshly prepared \(\mathrm{Fe}(\mathrm{OH})_{3}\) precipitate is peptised by adding \(\mathrm{FeCl}_{3}\) solution. The charge on the colloidal particle is due to preferential adsorption of:
1 \(\mathrm{Cl}^{-}\)ions
2 \(\mathrm{Fe}^{3+}\) ions
3 \(\mathrm{OH}^{-}\)ions
4 None
Explanation:
\(\mathrm{Fe}^{3+}\) is adsorbed.
