Talk:Chemical indicator

Isn't this article pathetically redundant to PH indicator? or is there some subtle difference i'm overlooking? The only article that links here (anymore) is talking about iodine being a chemical indicator for starch. however, that doesn't fit the definition here, of something undergoing a dissociation in a certain pH rage. I think this article should be scrapped. --Someones life 04:44, 8 March 2006 (UTC)
