Discussion Overview
The discussion revolves around the theoretical value for the heat of hydration of anhydrous copper(II) sulfate, specifically in the context of laboratory calculations. Participants explore the availability of thermodynamic data and methods for calculating the heat of hydration.
Discussion Character
- Technical explanation, Experimental/applied, Debate/contested
Main Points Raised
- One participant inquires about the theoretical heat of hydration for anhydrous copper(II) sulfate for laboratory calculations.
- Another participant clarifies that copper(II) sulfate exists in both anhydrous and pentahydrate forms.
- A participant expresses difficulty in finding thermodynamic data for the heat of hydration of anhydrous copper(II) sulfate, noting it is not available in their resources.
- This participant suggests calculating the heat of hydration using standard heats of formation for both the anhydrous form and the pentahydrate, mentioning potential complexities in the calculation.
- There is a question raised about which value to use for the water in the reaction, whether the heat of formation for water in its gaseous or liquid state should be applied.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the theoretical heat of hydration, and multiple competing views regarding the calculation methods and data availability remain unresolved.
Contextual Notes
Limitations include the lack of available thermodynamic data for anhydrous copper(II) sulfate and the ambiguity regarding the appropriate state of water to use in calculations.
