Property properties: red -brown liquid, relative density of 1.42, easy to dissolve with water, the aquatic solution is acidic, and has an aerobic and corrosion effect on metal. When diluted with iron -chloride solution, the hydroxide hydroxide precipitation is generated after hydrolysis, and it has a strong cohesion.
Using: Iron chloride is an important inorganic flocculant, which is characterized by the formation of alum flower density, easy to precipitate, and the effect of low temperature and low turbid water is better than aluminum salt. There are special effects of protein -containing wastewater such as alcohol and leather; in addition, it is also used for electronic etching, printing and dyeing drum engraving flowers and fabric dyes.
