[edit] solution

Is it a solution or what? It seems like its a mixture or suspension but it really isn't clear. Also, is it the same stuff that is used in ph paper?

Depends- you can make pH paper with pretty much any indicator. When I made a red cabbage indicator, we also soaked paper in it to make indicator paper. However, universal indicator paper is made from UI. -- Dandelions 13:35, 23 July 2006 (UTC)

[edit] poisonous?

Is it poisonous? If you put three drops in a drink then would it poison you? Thanks =)

I made technical changes to this article on 6/30/07. I was uncertain about Wikipedia article formatting. I would like to thank whoever cleaned up my formatting. Is there a writers guide that I should check out?

Universal indicator is a very popular educational tool, and the article is now technically sound. Thanks again to the format editor.

[edit] Is Aphex Twin relavant as a see also?

Shouldn't this be changed to a 'This article is about the acidity indicator, for the artist see Aphex Twin'? Jorourke92 (talk) 14:46, 7 February 2008 (UTC)
