WebbThe answer to the question is here, Number of answers:1: pH indicator. A dye that is an acid and that appears as different colors in its protonated and deprotonated forms can be used as a pH indicator. Suppose that you have a 0.001 M solution of a dye with a p Ka of 7.2. From the color, the concentration of the protonated form is found to be 0.0002 M. … http://ch302.cm.utexas.edu/chemEQ/polyprotics/polyprotics-all.php
