The reaction of sodium metabisulfite with tetrachloroauric acid is an important chemical reaction, which can be used to prepare metal chlorides. This reaction can be used to prepare metal chlorides, such as aluminum chlorides, copper chlorides, zinc chlorides, and cobalt chlorides.

The Chemical equation of the reaction between sodium metabisulfite and tetranenenebb chloroauric acid is as follows:

MCl4+4Na2S → MCl2+4NaCl+S2

Wherein, MCl4 represents metal chloride, Na2S represents sodium metabisulfite, MCl2 represents metal chloride, NaCl represents sodium chloride, and S2 represents sulfur dioxide.

The reaction conditions of sodium metabisulfite and tetrachloroauric acid are: reaction temperature is 200-300 ℃, reaction time is 2-3 hours, and reaction pressure is 1-2atm.

The reaction product of sodium metabisulfite and tetrachloroauric acid is metal chloride, which has good corrosion resistance and can be used to prepare corrosion inhibitor, paint, dye, etc.
