Which of the following process is not responsible for the presence of electric charge on the sol particles?A. Electron capture by sol particlesB. Adsorption of ionic species from solutionC. Formation of Helmholtz electrical double layerD. Absorption of ionic species from solution

Answer» Correct Answer - D
Absorption of ionic species from solution is not responsible for the presence of 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 despersion of metal.
(ii) preferential adsorption of ionic species from solution .
(iii) formation of Helmholtz electrical double layer.
