SUMMARY

The discussion centers on the concept of parts per million (ppm) concentrations, specifically questioning whether the concentration of a 50 ppm aqueous solution remains constant at 9.5 mL. It is established that concentration does not depend on the volume of the sample, similar to temperature remaining constant regardless of the volume of water. The conversation also touches on the distinction between intensive and extensive properties, emphasizing the importance of understanding these fundamental concepts in scientific discussions.

PREREQUISITES
  • Understanding of ppm (parts per million) concentration
  • Knowledge of intensive vs. extensive properties
  • Familiarity with basic chemistry concepts
  • Basic understanding of SI units
NEXT STEPS
  • Research the definition and applications of ppm in various scientific fields
  • Study the differences between intensive and extensive properties in detail
  • Explore concentration calculations in chemistry
  • Learn about the significance of SI units in scientific measurements
USEFUL FOR

Students in chemistry or physics, educators teaching concentration concepts, and professionals in scientific research requiring a clear understanding of concentration measurements.

I'm trying to get my head around the ppm concentration method. What is the conc. of 9.5mL of a 50 ppm aqueous solution? Is it still 50 ppm?

Im physics trained, so I'd rather see concentrations in SI units!

Any help appreciated.
 
Chemistry news on Phys.org
Since when any kind of concentration can depend on volume of the sample?

It is almost like asking "if I have 9.5 mL of 100 deg F water, does it still have 100 deg F"?

Do you know what is the difference between intensive and extensive properties?

Honestly - I don't understand how someone can claim to be physics trained and not understand such a basic concept.

And what do you mean by "ppm concentration METHOD"?
 
I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
