Acids and Bases

and stuff my textbook neglected. 


{ Engineering Notation, and etc }
x = given variable,  ____ = pattern marker
1 * 10 ^ (x) = 1 e (x)
5 * 10 ^ -92 = 5 e -92
[ ___ ] =  x = x mols / liter
[H20] = 5 = 5 mols / liter

{ Equilibrium Constant }
K = Ka [H2O], Kb [H2O]
Ka = [A-][H3O+] / [HA], acid dissociation
Kb = [BH+][OH-] / [B], base "dissociation", really association

{ P-scale }
p___= -log___ = x
p(cat) = -log(cat) = x
p(@) = -log(@) = x
pKa = -log Ka = x
10^ (@) = 10 ^(-log @) = -@
10^(pKa) = 10 ^(-log Ka) = -Ka



{ Ion-Constant for Water / Limits }
Kw = 1e-14
pKw = 14
Ka * Kb = Kw = 1e-14
pKa + pKb = pKw = 14

{ Hydronium &  Hyrdoxide }
[H30+] * [OH-] = 1e-14
pH30 + pOH = 14
pH = pH30

{ Definitions of Acid / Base }
Given the chemical formula,
A + B <=> C + D
if product contains:

[H30+ or  OH-], Arrhenius
[C + D], Bronsted-Lowry
[C (adduct) ], Lewis
