4
Q
pH
A
pH = -log[H+]
5
Q
[H+]
A
[H+] = 10^-pH
6
Q
pOH
A
pOH = -log[OH-]
7
Q
[OH-]
A
[OH-] = 10^-pOH
8
Q
pH + pOH
A
pH + pOH = 14
9
Q
Strong Acid & pKa
A
Stronger the ACID = Smaller the pKa
10
Q
Strong Base & pKb
A
Stronger the BASE = Smaller the pKb
11
Q
Exothermic
A
Release / Lose heat energy
12
Q
Endothermic
A
Need / gains heat energy
13
Q
Gibbs free energy
A
🔺G = 🔺H - T.🔺S
14
Q
Gibbs free energy and Spontaneity
A
🔺G<0 -> spontaneous
🔺G>0 -> NOT spont.
🔺G=0 -> EQUILIBRIUM
