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
