how do you calculate the concentration of H+ knowing OH and kw?
kw/[OH-]
the large the pKb
the less basic the soloution
the larger the pKa
the less acidic the solution
kw = ?
Kb x ka

HCL, HBr, HI, HNO3, HClO3, HClO4, H2SO4+
strong bases
group 1 and Ba, Sr, and Ca
cations
1) group 1A, 2A are neutral
2) small highly charged (acidic)
3) ammonium (acidic)
anions
1) conjugate of strong monoprotic acids (neutral)
(HCl, HBr, HI, HNO3, HClO3, HClO4 strong)
conjugate of weak acid
a) any anion is basic unless a conjugate of a strong base
