Storage condition
1. Store in dry and well-ventilated storeroom, do not mix with oxidant. Containers must be sealed to prevent contact with air from turning into copper oxide and reducing the value of use. Do not store and transport with strong acid, strong alkali and edible goods.

2. Handle with care during loading and unloading to prevent packing damage.

Stability 1. Will not decompose if used and stored according to specifications, no known hazard reactions, avoid oxides, moisture/moisture, air. 2. Form copper salt without dilute sulfuric acid and nitric acid. It turns blue quickly in the air. Soluble in concentrated alkali, ferric chloride and other solutions. Very poisonous! 3. Although stable in dry air, cuprous oxide will be slowly oxidized in wet air to produce copper oxide, so it can be used as a deoxidizing agent; In addition, it is easy to reduce it to copper with reducing agent. Cuprous oxide is insoluble in water, and ammonia water solution, concentrated halogen acid to form complex and dissolve, easy to dissolve in alkaline water solution.
Water is practically insoluble
