Why cant a component of binary solution ever be 100%

  • #1

Main Question or Discussion Point

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 cant 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 cant 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 cant "anything" be truly 100% thermodynamically pure?

Smells like homework --- ask yourself, "What's the logarithm of zero?"
