Difference Between Copper Hydroxide and Copper Oxychloride

Thekey differencebetween copper hydroxide and copper oxychloride is thatcopper hydroxide is an inorganic compound, while copper oxychloride is an organic compound.

Both copper hydroxide and copper oxychloride are important as fungicides. Copper oxychloride is useful mainly as a fungicide while copper hydroxide is an alternative for fungicides. Copper hydroxide is also used in the production of人造丝, a cellulose fibre. Moreover, copper hydroxide is a bluish-green solid while copper oxychloride is a green crystalline solid.

What is Copper Hydroxide?

氢氧化铜是具有化学配方cu（OH）的无机化合物₂. It is the hydroxide of copper. Moreover, this compound occurs as a bluish-green solid. It is a weak base. In the laboratory, we can also produce copper hydroxide by addingsodium hydroxideinto a dilute solution ofcopper sulfate(hydrated form). However, it occurs naturally as the mineral serpentinite.

此外,我们还可以依据ermine the structure of this compound using X-ray crystallography. Here, the copper atom is in the centre, and it has the geometry square pyramidal. The molar mass of this compound is 97.56 g/mol. The melting point is 80 °C, and it decomposes into CuO (copper oxide) upon further heating. Moreover, the solubility of this compound in water is negligible. When considering the uses of copper hydroxide, it is important in producing rayon, used in aquariums to destroy external parasites on fish, useful as an alternative for fungicides, etc.

什么是铜酰氯?

Copper oxychloride is an organic compound having the chemical formula Cu₂(OH)₃Cl. The IUPAC name of this compound is dicopper chloride trihydroxide. It occurs as a green crystalline solid. Moreover, we can find it in mineral deposits, metal corrosion products, archaeological objects, etc. In the industrial scale, we produce this compound to be used as a fungicide. The molar mass is 213.56 g/mol. Also, the melting point of this compound is 250 °C, and it is insoluble in water and organic solvents.

Naturally, copper oxychloride occurs in four different polymorphic structures: atacamite, paratacamite, clinoatacamite and botallackite. These different polymorphs have different crystal structures:

• Atacamite – orthorhombic
• 帕拉塔卡米特 - 菱形
• 腹膜钙化 - 单斜胶
• Botallackite – monoclinic

在220°C以上，这种化合物经历分解。在这种分解过程中，它消除了HCl酸。在中性培养基中，该化合物非常稳定。但是，如果它是一种碱性培养基，如果我们加热培养基，则该化合物分解，给出铜的氧化物。

What is the Difference Between Copper Hydroxide and Copper Oxychloride?

The key difference between copper hydroxide and copper oxychloride is that copper hydroxide is an inorganic compound, while copper oxychloride is an organic compound. Further, copper hydroxide appears as a bluish-green solid while copper oxychloride appears as a green crystalline solid.

Moreover, copper hydroxide occurs naturally as the mineral serpentinite while copper oxychloride occurs in mineral deposits, metal corrosion products, archaeological objects, etc.
