(a)
Interpretation:
Two different samples of NH4Cl dissolved in water was used for titration against 0.10 M NaOH or 0.10 M HCl,
- (a) The solution 0.10 M NaOH or 0.10 M HCl can be used to perform the titration has to be justified
- (b) The volume of titrant selected in part (a) that is needed to reach the equivalence point of the titration for each samples has to be calculated
- (c) The pH of the two solutions at the equivalence point of the titration has to be calculated
Concept Introduction:
Equivalence point:
The equivalence point in titration is the point where the amount of standard titrant solution (in moles) and the unknown concentration analyte solution (in moles) becomes equal.
In other words, the equivalence point is the point obtained in a titration once a stoichiometric amount of reactant has been added.
