Which of the following is present in the flask at the equivalence point if the ethanoic acid-sodium hydroxide titration? Explain your answers carefully.
A. CH3COOH (aq)
B. NaOH (aq)
C. CH3COONa (aq).

Solutions

Expert Solution

answer : CH3COONa

Explanation :

At equivalence point :

millimoles of acid = millimoles of base . so

CH3COOH   +   NaOH   ------------------> CH3COONa   +   H2O

        x                   x                                            0                 0

        0                  0                                            x

here salt only remains.

so CH3COONa is present at equivalence point
