Here's a lesson: "bye" is a word that means you're leaving. To say "bye" and not leave makes no sense.

Absolutely rediculous word. I could think of several ways to shorten it. Comment.
You should feel yoouself in the clouds if you take a little of this... 🙂
thats the name in spanish, and Im sure the english name doesn't differ too much.
But if you want a shorthand for it, is DDT 🙂
should be spread over this forums...
P.S.: if you don't know what a phenol group is, take ur elementary organic chemistry books, and re read them. You will making yourself a favour!
P.S.: I hope you take my comments with a little of salt.
Let's go Argentina! I want to see the result of Holland-Servia in a few hours!! I can't sleep!
Lol!
Cheers friend

What are you going to call it then? You have to call it something.
Phthalein also apparently describes something - a phenyl ring attached to a 5 membered ring with an ester group incorporated in the 5 membered ring.
Anyway my rec, friend.
Edit: btw, the phenolphthalein is an organic substance used with filter paper to determine the pH of a solution. At least. that was the main use I gave it when I was a kid... eras ago. 🙂

Originally posted by AThousandYoungIt's aroundabout pH 9 that it changes - above that pink, below that colourless. Easiest one to see the colour change, just unfortunately not suitable for two many reactions.

Originally posted by LittleBearIt is also quite common in foodstuffs, i'm not sure why, but is being phased out because of a link to cancer. Aromatic, organic compounds and all that malarky.

Originally posted by jimslyp69Phenol might be quite common in foods, but phenolphthalein isn't. And the vast majority of food contains organic compounds - pure table salt is the obvious exception.
