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
