Acid-base neutralization titrations:
When strong acid and strong base undergoes reaction gives salt
and water as products. The reaction is also called as acid-base
neutralization titration.
The standard solutions used in neutralization titrations are strong
aci da or strong bases for complete reaction and sharper end points.
(1) Usual acids are \(\mathrm{HCl}, \mathrm{H}_{2} \mathrm{SO}_{4}\) and perchloric acid as cold dilute
solution for safety.
(2) usual bases are \(\mathrm{NaOH}, \mathrm{KOH}\), and \(\mathrm{Ba}(\mathrm{OH})_{2}\)
Therefore, standard solutions for acid-base neutralization titrations are
\(\mathrm{NaOH}, \mathrm{HCl}\), and \(\mathrm{H}_{2} \mathrm{SO}_{4}\)
