Buffer Scenario
You have selected
your research project which
involves developing a porous
material that can be used for
glucose sensing in a basic
medium and requires that the
experiments be run at a pH of
9.7.
Start by looking at the following
three buffers and calculating their
pka and thus their buffer ranges.
Report all values to 1 decimal
place. [2 marks]
