Reactions of acids, bases, and acidic, basic, and neutral salts: Chemical Example rxn Strong acid HCl(aq) + H2O(l)  Cl- (aq) + H3O+(aq) Equili brium? no Weak acid HF (aq) + H2O(l)  F- (aq) + H3O+ (aq) yes Strong base NaOH(s)  Na+ (aq) + OH- no (aq) (does not react with water, dissolves in it) Weak base NH3(aq) + H2O(l)  OH- (aq) + NH4+ (aq) yes Acidic salt NH4Cl  NH4+ (aq) + Cl- yes (aq) (does not react with water, dissolves in it) In the beaker (picture) Cl-, H+ (products only) HF, F-, H+ (both sides) Na+, OH(products only) NH3, OH-, NH4+ (both sides) NH3, H+ , NH4+ Cl(both sides) then the non neutral ion (conjugate acid) reacts further with water NH4+ (aq) + H2O(l)  NH3(aq) + H3O+ (aq) Basic salt KF  K+ (aq) + F- (aq) yes HF, F-, OH-, K+ (both sides) no Na+, Cl(products only) (does not react with water, dissolves in it) then the non neutral ion (conjugate base ) reacts further with water F- (aq) + H2O(l)  HF (aq) + OHNeutral salt NaCl  Na+ (aq) + Cl- (aq) (does not react with water, dissolves in it) both ions are neutral so no further reaction (aq)
