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.

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.

2/11/2006, · The ,ferric hydroxide, precipitates maybe act through an adsorptive coagulating mechanism. Its structure provides a large adsorptive surface area and its positive electrostatic surface charge enables it to act as a powerful and efficient coagulant. However, at the pH beyond 11.0, the results show lower removal rate. This phenomenon is probably due to the increase in the solubility of ,ferric hydroxide, …

pH Adjustment and Neutralization the basics

The task of any pH adjustment system is to ,adjust, the pH of the process stream into the defined acceptable discharge range. In the case of an acid ,neutralization,, caustic (NaOH) is added to the effluent stream to pH Neutralize the solution. This ,neutralization,, or titration can be expressed as follows: HCl + NaOH → NaCl + H 2 O
