Section B. Acid–Base Equilibria and Indicator DyesSection C. Determination of the Ka Values of Weak Acid IndicatorsWatch the video associated with this section and summarize the procedure below. Make sure to include any observations you are able to make during the video. It is a good idea to read along in your Chemtrek. Bromocresol Green is an acid-base indicator that turns yellow in acidic conditions and bright blue in basic conditions.Watch the video associated with this section and read along in your Chemtrek. There are several observations you should be able to make in this section and it may be helpful to record your observations in a table.Reacting weak acid indicators with a variety of buffers from ph 1-12. Add 1 drop of Methyl Orange to each of the 12 wells and then add the coordinaing buffer with the well number (add pH buffer of 1.0 to well 1, pH buffer of 2.0 to well 2, etc.). Methyl Orange is red from wells 1-3, and then yellowish orange from wells 4-12. Bromocresol Green is yellow from well 1-3, green for well 4, blue for wells 5-12. Bromothymal Blue is yellow from well 1 to well 5, green for well 6, and blue from well 7-12. Phenolphthailein is clear from well 1 to well 9 and pink from well 10 to well 12.When adding a pH 4 buffer to bromocresol green of acidic, basic, and normal conditions the color of each well turns to the same light green color.
