Question

CuCI2 - Cu(OH)2 - CuSO4 ​

Answer 1

Ответ:

Объяснение:

CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl

Cu(OH)2 + H2SO4 = CuSO4 + 2H2O

Answer 2

The three chemical compounds you mentioned are all related to copper (Cu) and have different chemical properties:

1. CuCl2 (Copper(II) chloride): This is copper chloride, which exists in two forms: copper(II) chloride dihydrate (CuCl2·2H2O) and anhydrous copper(II) chloride (CuCl2). It is a blue-green crystalline solid. Copper(II) chloride is commonly used as a catalyst in various chemical reactions and also finds applications in the production of dyes, pigments, and wood preservatives.

2. Cu(OH)2 (Copper(II) hydroxide): This is copper hydroxide, a blue solid that forms when copper(II) ions react with hydroxide ions. It is not very soluble in water and has some applications as a fungicide and an algaecide in agriculture. Additionally, it is used in the preparation of Bordeaux mixture, which is a mixture of copper sulfate and calcium hydroxide used to control plant diseases.

3. CuSO4 (Copper(II) sulfate): This is copper sulfate, a blue crystalline solid that exists in two forms: copper(II) sulfate pentahydrate (CuSO4·5H2O) and anhydrous copper(II) sulfate (CuSO4). Copper(II) sulfate is commonly used in agriculture as a fungicide, in the electroplating industry, and in various chemical reactions. It also finds applications in educational demonstrations and laboratory experiments.

Overall, these compounds have diverse applications in different industries due to their unique chemical properties and reactivity with other substances.
