Comments: To: William Lipton
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)"

Question
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 It is not peer reviewed.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.

[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
