Hi everyone.

I'm doing a pre-lab for AP chem class. I forgot to check for specific data I need in the Merck. I was wondering whether anyone out there has the molar mass value and pKa of the indicator bromcresol green.

Any help would be great.
Thanks in advance.
 
Physics news on Phys.org
pKa = 4.7

At least that's what a website said :).
 
And its molecular formula is C21H14Br4SO5, so I trust you can figure out the molar mass.
