The packaging container of Cuprous Chloride must be complete and sealed. Do not store and transport with flammable materials and acids. Pay attention to moisture and rain during transportation. In the event of a fire, water, sand, and various fire extinguishers can be used to put out the fire, but firefighters should pay attention to the corrosiveness of caustic soda dissolved in the water.

The pure product with physical and chemical properties is colorless and transparent crystal with a relative density of 2.130. Melting point 318.4°C. The boiling point is 1390°C. Commercially available caustic soda has two types: solid and liquid: pure solid caustic soda is white, available in block, flake, rod, and granular, and brittle; pure liquid caustic soda is a colorless and transparent liquid. Solid caustic soda has strong hygroscopicity. Easily soluble in water, exothermic when dissolving, the aqueous solution is alkaline with a slippery feel; soluble in ethanol and glycerin; insoluble in acetone and ether. Very corrosive, corrosive to fiber, skin, glass, ceramics, etc. It reacts with metal aluminum and zinc, non-metal boron and silicon to release hydrogen; reacts with halogens such as chlorine, bromine, and iodine; and reacts with acids to neutralize salt and water.

When storing solid sodium hydroxide, keep it tight to prevent it from being exposed to the air to absorb moisture or deliquescence or carbon dioxide. When using glass bottles to hold 8-hydroxyquinoline Copper or other forms of sodium hydroxide, glass stoppers should not be used, and rubber stoppers should be used instead, because sodium hydroxide will react with the silica in the glass to form sodium silicate and cause bottle stoppers. Adhesive to the bottle body is not easy to open.
