What is the strength of an acid?
The percentage dissociation of an acid
Strong acid
100% dissociated and there are only 6 of them
All the Strong acids
HCl, HBr, HI, H2SO4, HNO3, HClO4
weak acids
those under 100% but most are less than 5%
Strength of Base
Percentage dissociation of that base.
All strong bases
LiOH, NaOH, KOH, RbOH, CsOH, Ca(OH)2, Ba(OH)2, Sr(OH)2
Autoionization of water and constatn at 25C
2H2O → H+ + OH- Kw = [H3O+][OH-] = 1.00 × 10^-14
pH
-log[H+]
pOH
-log[OH-]
