What are most buffers made of?

Conjugate acids and bases
Why do buffers use conjugate pairs?

Le Chatelier's principle
Find the pH of any acid base pair
Define equivalence point.
- Moles of added OH- equals original moles of H+
- pH of 7
Define endpoint

When the indicator changes colors.
Define the Q_sp of an ionic solute.
M_pX_q
- since the [M_pX_q] is constant (because it's a solid) you can multiply the Q_c by [solid] to get the Q_sp
- At equilibrium Qsp=Ksp
What does Ksp tell us?

The higher the Ksp the more soluble the substance
What is a complex ion?

A central metal ion covalently bonded to two or more anions or molecules.
What is a ligand?

The anions or molecules bonded to the central metal ion of a complex ion.
