Unformatted text preview: occurs: HC2H3O2 + OH- 6 H2O + C2H3O2- Since the strong base exactly neutralizes the weak acid (same concentrations
and same volumes), a solution containing a weak base (C2H3O2-) is formed. 0.5 M HCl + 0.2 M NaNO3
NaNO3 is a neutral electrolyte (NO3- is the conjugate base of a strong acid) so it
will not react with the strong acid HCl. A strong acid solution is formed. 1.0 M HNO3 + 2.0 M K2CO3
The following reaction occurs: CO32- + H3O+ 6 H2O + HCO3- Only one-half of the CO32- is converted to HCO3- (the CO32- concentration is twice
that of the acid), so a CO32-/HCO3- buffer solution is formed....
