Entropy
K’s. Ka x Kb = Kw
pKa = -log Ka
Ka = 10^-pKa
Titrations
Concentration = (gram/mol mass)/liter
Equivalence point = (molarity of titrant x liter titrant)/molarity other compound.

V eq Vs +Vt
At Veq: Ksp = [X] x [Y]. These 3 also count for titrations of strong acid and strong base.
After Veq. Vt-Veq=excess
Ionic strength Z -> p. 166
Activity alpha-> p. 166
Systematic treatment eq steps: p.172
- Write reactions (inculding H20->OH- + H+)
- Write charge balance(s)
- Write mass balance(s)
- Write equilibrium constant (K, Kw, Kb, Ksp) for each reaction (with activity coeff)
- Solve by substitution
Acid Base, monoprotic
