Subject: [DCHAS-L] pH Indicator Question
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.
