Practice Problem: Henderson-Hasselbalch Equation Calculations
David Hasslehoff did chemistry?! No wait, Hasselbalch. And Henderson. Anyway there's this equation, and it relates the pH of a buffer solution to the pKa of the acid and the ratio of the concentrations of the acid and conjugate base....

Buffers: Henderson-Hasselbalch Proof pH=pKa
Proof that pH=pKa when conjugate acid and base concentrations are equal; proof that conjugate acid and base concentrations are equal when pH=pKa

Atoms and their Interactions - The Chemistry of Life
In this section, I talk about elements, atoms and how they interact. I deal with two types of bonds: Covalent Bonds and Ionic Bonds. I also talk about pH, chemical reactions and metabolism.

Acid-Base Equilibria and Buffer Solutions
Remember those pesky iceboxes? Weak acids and bases establish equilibria, so we have to do iceboxes to figure out things about them. But don't worry, buffers are neat.
