Discussion Overview
The discussion centers around the solubility of CuI2 in water, with participants exploring related compounds and solubility rules. The scope includes theoretical considerations and chemical reactions involving copper and iodides.
Discussion Character
- Debate/contested
- Technical explanation
- Conceptual clarification
Main Points Raised
- Some participants suggest that CuI2 is insoluble in water, questioning how this fits with the general rule that iodides are soluble except for heavy metals.
- One participant proposes that copper might be considered a heavy metal.
- Another participant notes the lack of evidence for the existence of CuI2, complicating the discussion of its solubility.
- There is a mention of a reaction involving KI and CuSO4, with confusion about whether it results in a double replacement or no reaction.
- One participant claims that the reaction leads to a synthesis reaction and references a source indicating that CuI2 is insoluble, while expressing confusion about the solubility rules.
- Another participant challenges the reliability of the source that lists CuI2 as slightly soluble, suggesting it may not be accurate.
- There is a discussion about the oxidation of iodides by copper(II) in solution, leading to the formation of copper(I) iodide instead of CuI2.
Areas of Agreement / Disagreement
Participants express differing views on the solubility of CuI2, with no consensus reached. Some assert it is insoluble, while others question its existence and the reliability of sources regarding its solubility.
Contextual Notes
There are unresolved questions regarding the definitions of solubility and the specific behavior of copper in reactions with iodides. The discussion also highlights potential confusion between copper(I) and copper(II) iodides.
