Question

CrCl3-Cr(OH) 3-Cr2(So4)3-Cr(Oh)3​

Answer 1

Ответ:

CrCl₃ + 3KOH = Cr(OH)₃ + 3KCl

2 Cr(OH)3 + 3 H2SO4 → Cr2(SO4)3 + 6 H2O

Cr2(SO4)3 + 6NaOH --> 2Cr(OH)3 серо-зеленый осадок + 3Na2SO4

Answer 2

The compounds you mentioned are all related to chromium. Let's break down each compound:

1. CrCl3: This is chromium(III) chloride. It consists of one chromium ion (Cr3+) and three chloride ions (Cl-) to maintain charge balance. The chemical formula indicates that chromium is in the +3 oxidation state.

2. Cr(OH)3: This is chromium(III) hydroxide. It contains one chromium ion (Cr3+) and three hydroxide ions (OH-) to balance the charges. Chromium is in the +3 oxidation state here as well.

3. Cr2(SO4)3: This is chromium(III) sulfate. It consists of two chromium ions (Cr3+) and three sulfate ions (SO4^2-) to ensure charge neutrality. The oxidation state of chromium is +3.

4. Cr(Oh)3: The formula you provided seems to contain a typographical error. If it is corrected to Cr(OH)3, it is the same as the compound mentioned earlier, chromium(III) hydroxide.

In summary, the compounds you listed are chromium(III) compounds, where chromium is in the +3 oxidation state.
