use

Used in dyes, perfumes, mirrors, electroplating and other industries; and used as ultra-high pressure lubricating oil, bleaching agent, as reducing agent, mordant, decolorizing agent and analytical reagent, for the determination of silver, arsenic, molybdenum, and mercury. Strong reducing agent. Colorimetric determination of silver, lead, arsenic and molybdenum. Determination of inorganic phosphorus and alkaline phosphatase activity in serum. The molybdenum blue method determines the phosphorus content of soil and plants. Organic reaction catalyst.

Used as reducing agent, mordant, acidic tin plating, as the main salt. Used in the glass mirror industry, as a sensitizer for silver nitrate plating, to make the coating bright, and the coating of this product is not easy to fall off during ABS electroplating.
