[edit] Why does chemistry get to own this word?
Sorry for top-posting, but please justify... I accept that heterogeneous mixture and homogeneous mixture are widely used chemical terms, but even if the terms are most common in the sciences, i'm not really sure I like the word mixture coming to here. -- Redikufuk 18:16, 24 January 2007 (UTC) (please don't reply to my page, I never read it).
[edit] Is a salt solution a "mixture"?
The first line in the definition of mixture reads: "In chemistry, a mixture is the product of a mechanical blending or mixing of chemical substances like elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup."
In what way does dissociation of NaCl in an aqueous solution meet this criterion? What am I missing here? Solvation of sugar is quite a different case. TreeDoctor 04:14, 11 September 2006 (UTC)
yes, i also have the same doubt.our chemistry teacher told us about the disassociation of Na and Cl ions.this seems kind of chemical.then how can brine be a mixture?i'd appreciate an answer.Silver4 16:00, 20 February 2007 (UTC)
[edit] Other mixture related things
There is also the subtopic of suspension, physical reactions (e.g. heat, density, viscosity), or chemnical reactions (e.g. baking soda+vinegar) (and anything else?). In my science textbook there are way more topics about mixtures then listed her in wikipedia. If you are willing to help make this article less "stubby" please contribute because I have a test coming up about this.

[edit] A mixture of mixtures?
Hi, sorry to bother you, but my Chemistry instructor wants to know:
Can you have a mixture made up of mixtures?
Thanks, I'd really appreciate an answer.^_^
- uhh...yeah, of course. it'd still be a mixture thought. This kind of thing is best asked at our science reference desk/. Talk pages are more for discussion things to do with the article. --`/aksha 11:16, 25 January 2007 (UTC)
[edit] Combining Types Of Steel And Diamonds.
Sorry to bother all readers, (in case i'm doing that) but have any of you considered combining steel and diamonds together? For example: Titanium, Carbon steel, and diamonds, Combine them and what do you get: a new type of unbreakable steel! what would any of you name it? Personally I would name it "Meganite". My teacher said "Diamonite", but If Any of you have a better name Just say one and what it means.

- The closest one could get is to suspend diamond fragments in steel, a common practice. Otherwise, the highly stable structure which gives diamonds their strength would be lost. —The preceding unsigned comment was added by 75.69.118.1 (talk) 21:24, 15 March 2007 (UTC).

[edit] i need help in my chemistry and physics class
hey, sorry if im bothering you but im failing chemistry and physics i was hopeing for a few good free help sites for 7nth-8th grade chemistry and physics
thankyou
-Sunburn~Well I think the best thing for you to do is to keep a record of your past chemistry and physic's lesson's that way you won't fail any of those lesson's. for example: your record's will show you how to do them or what the answers were or whatever. Just be sure to keep your record's in a CPU file or a notebook or something.
...Your Welcome.
[edit] Contradictions
- In this article, colloids are said to never settle. But in the same breath, suspensions are said to be colloids. I'm not an expert, but isn't it more accurate to say that suspensions aren't colloids, but merely heterogeneous?
- The introduction equates homogeneous mixtures with solutions, in defiance of the rest of the article.
- This article says colloids are "both" homogeneous and heterogeneous. Now, they may exhibit characteristics of both types, but that doesn't matter. Homogeneity and heterogeneity, as defined here, seem mutually exclusive. The Colloid article seems to make it clear that colloids are heterogeneous.
- If you ask me, throughout this article, and its daughters, we ought to dissolve the separation of colloid and heterogeneous mixture. In many cases there are said to be three types of mixtures, and I think this is misleading.
- This article distinguishes "some alloys" from solutions, but AFAIK, all alloys are either solutions or compounds. The Alloy article takes this definition. Due to this change, another example of a homogeneous mixture that is not a solution will be needed.
I don't want to edit any of these myself, because I don't know enough to be sure.
