Estimation of pH - Postlab Questions

Postlab Questions

1. If you were asked to chose only two indicators from those we examined with which to perform this experiment, which two would you chose? Explain your choice.

2. List the solutions you tested in order of increasing basicity.

3. Solutions of baking soda and boric acid were prepared. When two drops of malachite green indicator were added to the boric acid solution it turned blue. When two drops of bromothymol blue indicator were added to the baking soda solution it also turned blue. Which solution has the higher pH?

This completes the experiment.
