If Industrial Grade Copper Sulfate Pentahydrate is exposed to humid air for a long time, especially in the rainy and humid weather in the south, it will slowly absorb the moisture in the air. After a period of time, CuSO4 and water will merge with each other until it dissolves into a saturated solution. It was completely deliquescence at this time. Therefore, after opening the package, we must keep it in a dry and sealed state to prevent deliquescence, which will affect the product quality and use effect.
If Industrial Grade Copper Sulfate Pentahydrate continues to be dry and accompanied by high temperature environmental conditions, the gradual loss of crystal water is very likely to produce white powdery CuSO4, which is the weathering phenomenon of Industrial Grade Copper Sulfate Pentahydrate. The first thing that is lost is the two water molecules that only bind with Cu2+ ions through coordination bonds. What is then lost are the two water molecules that not only bind with Cu2+ ions through coordination bonds, but also have a hydrogen bond with other water molecules. The hardest thing to lose is the water molecule that has 4 hydrogen bonds with SO42- ions and other water molecules. The process of weathering may seem simple, but the process of losing water molecules is more complicated and difficult to understand.
The hydrolysis of Industrial Grade Copper Sulfate Pentahydrate is closely related to the pH value and produces a basic copper salt. The difference in moisture and temperature is prone to deliquescence or weathering. Therefore, we must deeply understand the above properties in electroplating, sterilization, and industrial and agricultural production to avoid product failure.
