Explain how the minimum thickness of the resist layer can change
when taking into account doping concentrations in the ion-implanted
layers.
How can we measure the thickness of the colored layer for
colored hair ? You can take pieces.
Professor is looking for an in depth analysis of which
instrumentation/characterization is best for the question.
How does a buffer resist change in pH upon addition of a strong acid?
The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H^+ ions in solution and therefore only a little change in pH.

Predict how a buffer of HA and A- will resist change in
pH when a strong acid is added. Write down a reaction to represent
your prediction.
Acetic acid is CH3COOH, the Ka for acetic acid is
1.8x10-5.
Write the dissociation reaction for acetic
acid.
