Explanation / Answer
1) description of titration,
The technique of accurately measuring the volume of a solution required to react with another reagent
2) In the titration of a weak acid with a strong base, the point at which the number of moles of acid equal the number of moles of base is called,
equivalence point
3) at the ---, the pH = pKa
Half equivalence point
4) moles of NaOH used = 0.0987 M x 24.5 ml = 2.41815 mmol
Concentration of acetic acid = 2.41815 mmol/25 ml = 0.0967 M
0.0967 M
