Indeed, Wikipedia is NOT a reliable source.  I compared the Wikipedia list to a list published by Eastman some years ago and found many errors in that Wikipedia list.
 
I recommend thinking of Wikipedia as a sort of nickname for "Wicked impediment(ia)"

You raise an interesting question.  How much can we rely on Wikipedia as a reference?  It is not peer reviewed.  I recommend confirming any information from a more reliable source.

Subject: [DCHAS-L] pH Indicator Question

Hi All,

I'm in a bit of a pinch.  I think my pH meter is down in my lab and I
need to analyze some samples.

I need to titrate some phosphoric acid sample with sodium hydroxide
and I need a compatible indicator that will change at pH 9.  If anyone
knows off hand what that indicator is, please email me back and/or
call my cell phone at 516-633-3528.

Thanks,
Andrew Gross
