Question

Осуществите превращения согласно предложенной цепочки превращений CuSO4--Cu(OH)2--CuO.

Answer 1

CuSO₄ → Cu(OH)₂ → CuO.
1. CuSO₄ + 2KOH = Cu(OH)₂↓ + K₂SO₄.
2. Cu(OH)₂ t° → CuO + H₂O.

Answer 2

CuSO4+2KOH=Cu(OH)2 ↓+K2SO4
Cu(OH)2=СuO+H2O

Answer 3

Transformation of CuSO4 to Cu(OH)2 to CuO

To transform CuSO4 to Cu(OH)2 to CuO, we can follow the following chemical reactions:

1. CuSO4 to Cu(OH)2: - The chemical reaction for this transformation is: CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4 - This reaction involves the use of sodium hydroxide (NaOH) to precipitate copper hydroxide (Cu(OH)2) from copper sulfate (CuSO4) [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap).

2. Cu(OH)2 to CuO: - The chemical reaction for this transformation is: Cu(OH)2 = CuO + H2O - This reaction involves the decomposition of copper hydroxide (Cu(OH)2) to form copper oxide (CuO) and water (H2O) [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap).

Therefore, the overall transformation from CuSO4 to Cu(OH)2 to CuO involves the use of sodium hydroxide to first precipitate copper hydroxide from copper sulfate, followed by the decomposition of copper hydroxide to form copper oxide and water.
