Talk:Dilution ratio

Probable ERROR
Nowadays it is written 1:5 would be 5e−1 but I think it is 2e−1. — Preceding unsigned comment added by Alexor65 (talk • contribs) 17:29, 17 October 2018 (UTC)

Contested deletion
This page should not be speedy deleted as an unambiguous copyright infringement because the text originated in the Wikipedia article Ratio. The copyright violation is, in fact, the other way round. The answer given in 2011 was an exact copy of the Wikipedia section (but no attribution was given to Wikipedia). Some of the wording is mine from January 2010.

Contradictory article
It says that dilution ratio and factor is the same, and then it says there is confusion and gives two definitions for them, one to be a pure solvents ratio, the other a ratio of initial vs final. So then what's going to be? Are they two different things? Or they're the same thing and then the use of a pure ratio should be labeled as a mistake?

The article needs to clarify it — Preceding unsigned comment added by 84.89.157.200 (talk) 08:37, 18 February 2016 (UTC)


 * Yes, this article is actually about dilution factor, but there is common confusion because this factor is commonly expressed as a ratio. How can we make this clearer?    D b f i r s   23:00, 2 June 2016 (UTC)

Definition of Dilution Factor
I have found different definitions online, but my understanding is that dilution factor is the inverse of dilution; e.g. if you add 0.1 mL of broth culture to 0.9 mL of dilutent, you end up with a 1/10 or 1:10 dilution but a dilution factor of 10. Even the linked article says this. However, the article also says that if you go from a less concentrated to more concentrated, the dilution factor can be less than zero.
