Ferric Hydroxide Sol (hydrolysis): Preparation - QS Study

A, brilliant dark red sol is produced by, the, hydrolysis of ferric chloride forming ferric hydroxide, and hydrochloric acid. Ferric hydroxide forms a hydrophobic sol. Take 50 ml of distilled water in a beaker and heat it to about 100°C. Add the sol of FeCI3 to water with stirring. Hence it is prepared indirectly by the hydrolysis of ferric chloride with boiling water.

The third step involves the hydrolysis of ferric iron with water to form the solid, ferric hydroxide, (ferrihydrite) and the release of additional acidity. This third reaction is Ph dependent. Under very acid conditions of less than about Ph 3.5, the solid mineral does not form and ferric iron remains in solution.
