Predict whether each solution will be neutral, basic, or acidic at the equivalence point of each titration.
a. An aqueous solution of NaOH is titrated with 0.100 M HCl.
b. An aqueous solution of ethylamine (CH3CH2NH2) is titrated with 0.150 M HNO3
c. An aqueous solution of aniline hydrochloride (C6H5NH3+Cl−) is titrated with 0.050 M KOH.
Homework Answers
a. An aqueous solution of NaOH is titrated with 0.100 M
HCl.
since reaction is between strong acid and strong base, solution
will be neutral at equivalence point
b. An aqueous solution of ethylamine (CH3CH2NH2) is
titrated with 0.150 M HNO3
since reaction is between strong acid and weak base, solution will
be acidic at equivalence point
c. An aqueous solution of aniline hydrochloride
(C6H5NH3+Cl−) is titrated with 0.050 M KOH.
since reaction is between weak acid and strong base, solution will
be basic at equivalence point
