A jar test is ideal to asses the influence of these process parameters within a short time. Adding ferric chloride causes a number of hydroly sis reactions, where the iron ions react as an acid, thereby reducing the pH. As a result of these reactions iron hydroxide already precipitates in an acidic environment.
