boshdosh Posted September 27, 2009 Posted September 27, 2009 my science teacher has asked us to come up with 4 common indicators and i havent got a clue, i know about red cabbage but what else??? plz help
dr.syntax Posted September 27, 2009 Posted September 27, 2009 (edited) Does it have to be a natural plant ? Maybe there is something in your mother`s cleaning cabinet you can think of. Another source might be where she stores baking supplies and pickleling supplies. ...DS Edited September 27, 2009 by dr.syntax additition
UC Posted September 27, 2009 Posted September 27, 2009 Google is your friend. http://en.wikipedia.org/wiki/PH_indicator Phenolphthalein is probably the most common in science labs. Bromothymol blue is also popular, and obviously Litmus.

CharonY Posted September 27, 2009 Posted September 27, 2009 Shouldn't someone have asked "common indicator of what?" Red cabbage could also be an indicator of diner... Learning how to ask question precisely is also a valuable skill.

Learning how to ask question precisely is also a valuable skill. Hehe. Here I thought, what with answers being given, there was some other meaning for "indicator" that I wasn't aware of. Ok, I'll ask: Indicator of what? Gimmeh sum contekst!
