Question

Проделать реакции подтверждающие качественный состав сульфата меди 2

Answer 1

СuSO4+BaCl2=BaSO4(осадок)+CuCl2 \Доказательство наличия сульфат-иона\
СuSO4+2KOH=Cu(OH)2(осадок)+K2SO4 (Доказательство наличия иона меди(2). Осадок при слабом нагревании разлагается с образованием черного оксида меди(2)
Cu(OH)2=t=CuO+H2O\

Answer 2

Testing the Quality of Copper(II) Sulfate

To confirm the quality of copper(II) sulfate, you can perform several reactions that are characteristic of its composition. Here are some reactions that can help confirm the presence of copper(II) sulfate:

1. Reaction with Sodium Hydroxide (NaOH): When copper(II) sulfate reacts with sodium hydroxide, it forms a blue precipitate of copper(II) hydroxide. Source: Mar 9, 2021 ... , . 4. - ... 500 (II), 50%, 100 .

2. Reaction with Barium Chloride (BaCl2): The reaction of copper(II) sulfate with barium chloride results in the formation of a white precipitate of barium sulfate. Source: Feb 8, 2019 ... , -, , , , ... Ra2+, Na2+, C)2-3) , ...

3. Reaction with Iron: Copper(II) sulfate can also react with iron to form copper metal and iron(II) sulfate. Source: Title: ' ' Snippet: ``` , - . -...```

These reactions can help confirm the presence of copper(II) sulfate based on the characteristic products formed.
