4)H 3 O + + NO 2 - H 2 O + HNO 2 5)Includes non-aqueous systems NH NH NH 3 D.Solvent System Concept 1)Useful for aprotic, non-aqueous systems 2)Applies to any solvent that can dissociate to cation (acid) and anion (base) 3)For water: 2 H 2 O H 3 O + + OH - a)Any solute increasing [H 3 O + ] is an acid HCl + H 2 O H 3 O + + Cl- b)Any solute increasing [OH - ] is a base NH 3 + H 2 O NH OH - 4)Aprotic, non-aqueous example: 2 BrF 3 BrF BrF 4 - a)Acid: SbF 5 + BrF 3 BrF SbF 6 - b)Base: F - + BrF 3 BrF 4 - 5)The acid-base reaction: acid + base = solvent (reverse of the ionization) a)Arrhenius: acid + base = salt + water b)Bronsted: acid1 + base2 = base1 + acid2
