Ferric chloride is a typical compound in chemistry. The molecular formula is FeCl3. What are the physical and chemical properties of ferric chloride?

First of all, starting from the physical properties of ferric chloride, ferric chloride is generally a black brown solid, and this solid is a crystalline form. Although it does not seem to be crystal clear, it can also be clearly observed the crystalline state. Ferric chloride also has enhanced physical stability, can withstand the test of high temperature in the environment, and will not produce color, morphology and other changes, and maintain the original physical and chemical properties of ferric chloride.

The chemical properties of ferric chloride are more complex than the physical properties. Ferric chloride has a very strong oxidizability, which is easy to deteriorate when exposed to air, resulting in the deterioration of ferric chloride. And the crystalline ferric chloride will agglomerate because it is exposed to the air. At this time, it will lose its crystalline state and become black block. Ferric chloride can react with many metal elements, such as aluminum, zinc, copper, etc., which is also one of the important use principles of ferric chloride. It can replace many metals in industrial production.

In water treatment, the oxidation of ferric chloride and ferric hydroxide colloid produced by hydrolysis are the main action principles. Ferric hydroxide colloid produced by hydrolysis of ferric chloride can flocculate most pollutants in sewage polar, and strong oxidation can remove organic matter, color, oil and so on.

The strong oxidizability of ferric chloride is also the main reason for becoming dangerous goods, so more attention should be paid to its use and storage.
