A 25.0 mL of a solution of acetic acid of unknown concentration is titrated with 0.09926 M NaOH and the equivalence point volume was determined by graphical means to be 22.4 mL. What is the concentration of the acetic acid?

The concentration of acetic acid is 0.0889 M

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is NaOH.

We are given:

Putting values in above equation, we get:

Hence, the concentration of acetic acid is 0.0889 M

ok whats the question if not i cannot you i need question and need a thing to answer
