The color of magnesium chloride tablets is generally white and yellow, mainly bleached with sodium hypochlorite solution. The impurities in the precipitate are the same as those in sodium sulfate, so the content of the two is not much different. After production tests, the content of magnesium chloride white tablets and magnesium chloride yellow tablets is basically the same, and the content of magnesium chloride white tablets will be reduced.
Currently, most manufacturers use sodium hypochlorite to react with a solution of magnesium chloride to produce precipitation and bleach. The color of magnesium chloride produced by bleaching magnesium chloride solution varies greatly, but the composition of yellow magnesium chloride tablets and white magnesium chloride tablets is not significantly different, and the product quality is basically the same. Therefore, the user does not have to be too nervous, but sodium hypochlorite makes it slightly corrosive, so magnesium chloride tablets add liquid drugs can not be used as tofu products.
Magnesium chloride tablets also vary in color due to different origins. Whether the color is white, brown or yellow, it is independent of the content, and the content of magnesium chloride and the amount of precipitation mainly depend on the transparency of the magnesium chloride tablets.
