[edit] Indicator chemicals

The indicator chemical links all return the user to this page, which tells us nothing about the individual chemical structures, properties, etc. These need to be broken out like other chemicals. —Preceding unsigned comment added by 64.90.124.37 (talk) 18:44, 21 March 2008 (UTC)

[edit] Method of measuring ph value using litmus papers

on my report it says place a fresh piece of blue litmus paper in a becker of water.using a straw,blow gently into the water for several minutes,until a change in the litmus paper occurs.what does the change show about exhaled breath when it dissolves in water?

And what do you want to know?T.vanschaik 21:53, 23 October 2006 (UTC)

If you exhale into the water and it shows an acidic change, it's likely carbonic (or should that be carboxylic? I forget) acid formed by the dissasociation of CO2 in water. 69.210.62.227 04:45, 30 November 2006 (UTC)

Yes, it's carbonic acid, but the report asks the student to do a simple experiment so the logical thing would be to actually do it.

[edit] the same as "indicator strips"?

is litmus paper analogous to "indicator strips" that my textbook talks about? whoops, forgot to sign. --69.120.54.32 12:32, 6 May 2007 (UTC)

Nobody seems to use capital letters anymore... Litmus is a type of pH indicator. There are many of them, some of which come in the form of strips of paper soaked in the indicator compound. Richard001 06:24, 26 May 2007 (UTC)
