Title: Is there a way to infer the maximum dilution of a substance?
Post by: scientizscht on 01/09/2022 23:51:00

Hello

Any idea what would be the maximum dilution of a powder of 50-200μm particles with density 0.5g/mL?

Any even rough estimate? I am wondering if 1 gram can be easily diluted to 1 gram of water and the solution can be usable in terms of reactivity and diffusivity?

Thanks!

If you mixed a gram of stuff into the nearest lake it would be very dilute.
If you mixed it into the ocean it would be even more dilute.
There is no "maximum dilution".

Do you mean a maximum concentration?

That's less dense than lithium.
What are they made of?
Are they hollow?

According to homeopaths, there is no limit to the dilution you can achieve.
- They even have a process ("potentisation") that can dilute a substance until no molecules of the original substance remain - and still keep diluting it further!

Oh sorry yes I meant concentration. Also particles are not hollow. Any hints?

Realistically, someone would have to do the experiment (unless it has already been done).

Yes of course, just wanted to ask if anyone had similar experience or even what is the maximum concentration of an analogue substance e.g. a protein? Just looking to get an indication of magnitude.
