average pKa = 7.81
image text in transcribed
The calculations in this lab assume that esentially 100% of the the phenol red in Tube \#2 is in its conjugate base form. - Calculate the B/A ratio of phenol red in Tube \#2 (use your average pKa and assume the NaOH solution has a pH=12). - Show the calculation. - Use the answer to determine if the assumption is valid. Is the phenol red in Tube \#2 essentiall 100% conjugate base
