About this document

Bromophenol Blue Ka Determination by Derek Young is a document available to read on EtoBox.

This document describes an experiment to determine the ionization constant (Ka) of the weak acid bromophenol blue using spectrophotometry. Absorption spectra of bromophenol blue solutions at varying pH levels are measured to determine the optimum wavelength for analysis. Standard solutions of known bromophenol blue concentrations are then used to construct a calibration curve relating absorbance to concentration. The concentration of an unknown sample is determined using the calibration curve and absorbance
