Acids, Bases, Cation Oxidation Numbers, Polyatomic ions Flashcards
Define strong acids
completely ionized in water to give one (or more) protons per acid molecule
Name the 7 strong acids and how they dissociate
HI: H+(aq) + I-(aq)HBr: H+(aq) + Br-(aq)HClO4: H+(aq) + ClO4-(aq)HCl: H+(aq) + Cl-(aq)HClO3: H+(aq) + ClO3-(aq)HNO3: H+(aq) + NO3-(aq)H2SO4: H+(aq) + HSO4-(aq) (HSO4- is a weak acid that contributes additional protons)
Define strong bases
completely ionized in water to give one (or more) hydroxides per base molecule
Name the 8 strong bases and how they dissociate
NaOH: Na+(aq) + OH-(aq)KOH: K+(aq) + OH-(aq)LiOH: Li+(aq) + OH-(aq)RbOH: Rb+(aq) + OH-(aq)CsOH: Cs+(aq) + OH-(aq)Ca(OH)2: Ca+2(aq) + 2OH-(aq) (but not very soluble)Ba(OH)2: Ba+2(aq) + 2OH-(aq) (but not very soluble)Sr(OH)2: Sr+2(aq) + 2OH-(aq) (but not very soluble)
