Ferric hydroxide sol can be prepared from freshly prepared ferric hydroxide precipitate. It can also be prepared by adding ferric chloride solution to boiling water. In both cases the sol particles are positively charged. What happenswhen an electric pot ential is applied across two platinum electrodes dipping in" ferric hydroxide sol? Explain.

Ferric hydroxide sol can be prepared from freshly perpared ferric hydroxide precipitate. It can also be prepared by adding ferric chloride solution to boilling water. In both cases the sol particles are positively charged. Name the above two methods of preparation of ferric hydroxide sol.

Assertion: A sol of As_2S_3 prepared by the action of H_2S on As_2O_3 is negatively charged. Reason: It is due to the absorption of H^+ ions on the surface of the colloidal particle and S^(2-) ions in the diffused layer.
