Discussion Overview

The discussion centers around the question of why a component of a binary solution cannot be 100% pure, with a focus on thermodynamic explanations, equations, and graphs. Participants explore the implications of purity in binary solutions and the broader concept of purity in solutions.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested, Homework-related

Main Points Raised

  • One participant questions whether a component can be 100% pure without the other component being 0%, suggesting that this would contradict the definition of a binary solution.
  • Another participant reframes the question to consider why anything can be "truly" 100% pure, indicating a broader inquiry into the concept of purity in thermodynamics.
  • A further clarification is made regarding the wording of the question, emphasizing the impossibility of achieving 100% purity in a binary solution while still maintaining the definition of the components involved.
  • One participant hints at a mathematical consideration by referencing the logarithm of zero, implying a potential connection to the discussion of purity and thermodynamic principles.

Areas of Agreement / Disagreement

Participants express confusion and seek clarification on the original question, indicating that there is no consensus on the phrasing or understanding of the concept of purity in binary solutions. Multiple perspectives on the nature of purity and its implications remain present.

Contextual Notes

Participants have not yet provided specific thermodynamic equations or graphs, and the discussion remains at a conceptual level without resolving the underlying assumptions about purity and definitions.

Who May Find This Useful

Individuals interested in thermodynamics, solution chemistry, or those seeking to understand the complexities of purity in binary solutions may find this discussion relevant.

I need to learn and understand why a component of a binary solution cannot be 100%. This needs to be done thermodynamically with equations. I can not find much online, and i need good detail of equations and graphs.

Thanks if you can solve.

Well wouldn't that mean the other component is 0%? Then wouldn't that mean the solution isn't binary?
 
Oh yes, that is very confusing. I got you all mixed up haha. The question should be stated, "why can't anything ever be "truly" 100% pure?" Considering a binary system show thermodynamically how this is impossible with equations or graphs etc. Sorry mistake
 
Although, i guess you could say, why can't a binary solution (say A-B) be 100% pure ... of A-B. So technically it is worded correctly but the point is the same. Why can't "anything" be truly 100% thermodynamically pure?
 
Smells like homework --- ask yourself, "What's the logarithm of zero?"
