Acidimetry and alkalimetry titration

• Acidimetry and alkalimetry are two common types of titrations used to determine the concentration of acidic or basic solutions, respectively.
• Acidimetry and alkalimetry involve the use of an acid or a base as the titrant to react with the analyte, which is either a base or an acid, respectively.

1. Acidimetry:

• Acidimetry is a titration process that involves the determination of the concentration of a basic (alkaline) solution by titrating it with a standard solution of a strong acid (the titrant).
• The acid neutralizes the base until the equivalence point is reached, at which point the moles of H+ ions from the acid are equal to the moles of OH- ions from the base.
• The endpoint of the titration is usually detected using a suitable indicator, which changes color at a specific pH.

• Example:

  • A common example of acidimetry is the titration of a sodium hydroxide (NaOH) solution with a hydrochloric acid (HCl) solution of known concentration.
  • The chemical reaction is as follows:

NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l)

2. Alkalimetry:

• Alkalimetry is a titration process that involves the determination of the concentration of an acidic solution by titrating it with a standard solution of a strong base (the titrant).
• The base neutralizes the acid until the equivalence point is reached, at which point the moles of OH- ions from the base are equal to the moles of H+ ions from the acid.
• The endpoint of the titration is typically detected using a suitable indicator, which changes color at a specific pH.

• Example:

  • A common example of alkalimetry is the titration of a hydrochloric acid (HCl) solution with a sodium hydroxide (NaOH) solution of known concentration.
  • The chemical reaction is as follows:
• HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l)
