I thought tonicity referred to the solution with reference to the cell. i.e. 7% sodium chloride solution would be a hypertonic solution with respect to almost all living cells. 81.179.75.219 07:50, 3 July 2006 (UTC)

Tonicity is a unitless comparison of the solute concentration of one solution to another. Although it is often used to describe the solute concentration of extacellular fluid relative to the intracellular fluid, it need not be used this way. Tonicity can be expressed between any solutions separated by a semi-permeable membrane. I hope that this clears things up for you Slevit1 (talk) 20:10, 20 February 2008 (UTC)

I am really confused about this page. I feel it is really off the reality according to what I read elsewhere at http://www.biotech.ufl.edu/EM/data/osmos.html Could an expert verify? --The PA 02:56, 7 September 2006 (UTC)

What, exactly, do you think is contradictory? Slevit1 (talk) 20:10, 20 February 2008 (UTC)

i dont think this page should be merged with osmoles

[edit] Merge proposal

I'm proposing to merge isotonic, hypotonic, and hypertonic into this article. I think having several sections for these terms in here would be sufficient. - tameeria (talk) 20:16, 9 December 2007 (UTC)

Addendum: Per Wikipedia:Naming conventions, article names should be preferably nouns and adjectives should be redirects to nouns. In this case, "tonicity" is the noun that fits all of these adjective titles. - tameeria (talk) 04:44, 11 December 2007 (UTC)

• The merge makes sense to me--the content of each is essentially redundant and could be better served as a single topic with several redirects. I'll help w/ the merge if it goes forward... — Scientizzle 22:06, 11 December 2007 (UTC)

I'd agree with merging. One really can't understand any of the concepts without reference to the other two. The background material is going to be the same for all three. And when there get to be more refs, most of them will be relevant to all three.

As for the name, gee, if a gin'n'tonic is a noun, then wouldn't an isotonic be one too?  :-)

*lol* Maybe there should be a page for isotonic (beverage)? :-) Actually, there is one for isotonic (exercise physiology) since the term is used for muscles, too. And then there's isotone and isotonic regression as well, so there probably needs to be some sort of disambiguation. - tameeria (talk) 02:16, 12 December 2007 (UTC)

I agree with the merging also. Forluvoft (talk) 17:02, 12 December 2007 (UTC)

Merging, good idea. Tim Vickers (talk) 17:14, 12 December 2007 (UTC)

I'll get about merging them, then. Master of Puppets _{Call me MoP!☺} 00:36, 17 January 2008 (UTC)

[edit] How should this be incorporated?

I want to add information, but I'm not quite sure as to how to make it fit with the rest of the article. Basically, this entire article refers to tonicity between a cell and its external environment. However, tonicity does not have to relate to a cell. For example, a hypertonic solution is simply one with a greater impermeable solute concentration than the solution to which it is being compared. You can separate any two fluids with a semi-permeable membrane and have one be hyper/hypo/isotonic to the other. This is often used in reference to a cell, but does not need to be. Any ideas on how to incorporate this? Slevit1 (talk) 15:29, 21 February 2008 (UTC)
