Discussion Overview
The discussion revolves around the solubility of Cu2+ in the presence of Cl- ions, specifically examining how the charge and size of the copper ions affect their solubility. Participants explore the implications of different oxidation states of copper (Cu+ vs. Cu2+) and the role of the solvent in determining solubility.
Discussion Character
- Debate/contested
- Technical explanation
Main Points Raised
- One participant questions whether Cu+ and Cu2+ are treated the same regarding solubility, referencing a solubility chart that indicates low solubility for Cu+.
- Another participant emphasizes that solubility is dependent on the solvent and cannot be generalized without specifying it, suggesting that all substances have some level of solubility defined by the solubility product.
- A participant provides a link to a solubility table, noting that it includes Cu+ but not Cu2+, and seeks clarification on how different oxidation states affect solubility.
- One participant argues that Cu(II) should not be assumed to have similar solubility to Cu(I) due to differences in charge density and hydration energy, which may influence solubility.
- A suggestion is made to look up Latimer's equation to understand the empirical relationship between solubility, charge, and size of ions.
Areas of Agreement / Disagreement
Participants express differing views on the solubility of Cu2+ compared to Cu+, with no consensus reached on whether they should be treated similarly. The role of the solvent in determining solubility is also a point of contention.
Contextual Notes
The discussion highlights the importance of specifying the solvent when discussing solubility and the potential variations in solubility based on the oxidation state of copper ions. Limitations in the provided solubility chart and the assumptions made by participants are noted but not resolved.
