Acids
Proton Donors create conjugate bases
Proton Receivers create conjugate acids
These are __________ theory
Bronsted–Lowry acid–base theory
What is the base disassociation expression? What is an example of it (write the base disassociation expression in terms of a strong base)
B → HB+ + OH-
What makes up a buffer solution? Provide an example of species involved.
Why is the pH of your body regulated so precisely?
To allow that body part to function properly.
Calculate the pH of 0.00200 M solution of perchloric acid, HClO4.

Example of a natural buffer and its use?
Carbonic acid prevents acidification of blood
Calculate the pH of a solution that is composed of 90.0 mL of 0.345 M sodium hydroxide, NaOH, and
50.0 mL of 0.123 M lactic acid, HC3H5O3. (Ka of lactic acid = 1.38x10-4)

Why does drinking water prevent Alkalosis?
- water dilutes blood, lowering the OH concentration in blood
What is a real world example of buffer solutions that were not described in this presentation? (NOT blood, organs in the body, or limestone)
