【 摘 要 】
Problem statement: Bromophenol blue is a pH indicator, a kind of chemical that changes color when pH goes up or down over a narrow linear dynamic range of 3.0-4.6 pH units. Therefore a good approach must be taken to extend the linear response of the indicator in order to have simple calibration and precise measurements of PH sensors. The purpose of this experiment is to measure the nonlinear refractive index of Bromophenol blue in a PH range of 2-9. Approach: Samples of Bromophenol blue solutions at an optimized final concentration of 5.25
