This experiment has the student using spectrophotometry to measure the pKa of an acid-base indicator bromocresol green. Given that the pKa value of BCG given by literature is 466 the experimental pKa of bromocresol green must be greater than 4427 and less than. NB You can look up the molar mass of bromocresol green in the Merck Index under bromcresol green note the spelling difference.
Here is all you need to learn about determination of pka of bromocresol green Ia a bi A - A pK pH - log A - A Table IV. When dissolved in water the conjugate pair acid ic and basic forms display different absorption spectra since they possess different colors. The pKa of 3355tetrabromo-m-cresolsulfonephtalein Bromocresol Green and o-cresolsulphonephtalein Cresol Red was spectrophotometrically measured in a waterAOTisooctane microemulsion in the presence of a series of buffers carrying different charges at.
