Pre-Laboratory Questions Calculate the concentrations of the protonated and unprotonated forms of bromothymol blue in 100 mL of a pH 8.1 buffer solution to which 1.0 mL of a 0.005 M solution of bromothymol blue in 80%water/20%ethanol has been added. Calculate the pH of the buffer solution that results when 10 mL ofo.10 M NaH_2PO_4 is added to 3 mL of 0.05 M NaOH.
