Question 7:Explain why the solutions turned green, instead of blue or yellow when you added the buffer at pH4. Approximately what are the relative concentrations of Inand HIn in the three wells?
Section D. pH Measurement with Indicator Color ProbesSection E. The Study of Acid–Base Equilibria by Graphical Interpretation of Titration DataSection E. Part 1. Titration of a Strong Acid with a Strong BaseQuestion 8: What is the net ionic equation for the reaction between HCl and NaOH? 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. Create a titration curve using the data from the video and attach the titration curve at the end of this section. 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. You may need to reference back to this video and observations for future sections. A Universal Indicator that is a combination of several common acid-base indicators. This indicator is used when the equivalence point pH is unknown.Well 1 – redWell 9 – dark blueWell 2 – orangeWell 10 – dark blueWell 3 – orange/yellowWell 11 – dark purpleWell 4 – yellowWell 12 – dark purpleWell 5 – yellow/greenWell 6 – yellow/greenWell 7 – greenWell 8 – dark green
