Характеристики

Boric Acid magic fish scale flakes and chunks

Boric acid is a kind of white powdery crystal or scaly luster crystal on triaxial plane.It has a greasy feel and no odor. Soluble in water, alcohol, glycerin, ethers and essential oils. No smell. The taste is slightly sour and sweet after bitter. Greasy feeling in contact with skin. No change in exposed air. It can volatilize with water vapor. When heated to 100 ~ 105 ℃, one molecule of water is lost to form metaboric acid. When heated at 104 ~ 160 ℃ for a long time, it is transformed into pyroboric acid, and anhydrous matter is formed at higher temperature. The pH of 0.1mol/l aqueous solution is 5.1. 1g can be dissolved in 18ML cold water, 4ml boiling water, 18ML cold ethanol, 6ml boiling ethanol and 4ml glycerol. The solubility in water increases with the addition of hydrochloric acid, citric acid and tartaric acid.
