Additional Information:
The following information will be provided on the exam:
K = °C + 273
at 25 ° C, Kw = 1.0 x 10-14
at 25 ° C , pH + pOH = 14
pH = -log [H3O+]
pOH = -log [OH-]
pKa = -log Ka
Ka x Kb = Kw
[H3O+] = Ka( [acid] / [conj base] )
Strong Acids: HCl, HBr, HI, HNO3, HClO4, H2SO4 (Assume all other acids are weak.)
Strong Bases: NaOH, KOH, Ba(OH)2
qP = DH
DH° = SDH°f
(products) - SDH°f
(reactants)
DSuniverse = DSsystem
+ DSsurroundings ³
0
DS = qreversible / T
DSsurr = - DHsys
/ T
DS° = SS°
(products) - SS°
(reactants)
