The titration curve varies with different acid-base titrations because it is influenced by various factors such as the strength of the acid and base, their concentrations, and the dissociation constants. These factors can affect the shape of the curve, including the equivalence point and buffering regions.
The titration curve obtained in titration of HCl against NaOH is a typical acid-base titration curve. It shows a gradual increase in pH at the beginning due to the addition of base (NaOH). At the equivalence point, the curve shows a sharp increase in pH since all the HCl has been neutralized. After the equivalence point, the pH continues to rise as excess NaOH is added.
The product of a titration is a titration curve, which is a graph showing the pH or volume of titrant added against the concentration of the analyte in a solution. The shape of the curve can reveal information about the equivalence point, endpoint, and buffering capacity of the solution.
The shape of the titration curve for complexometric titration typically shows the formation of a sharp endpoint or plateau where the metal ions are completely complexed by the titrant. This results in a sudden change in the pH or other titration parameter being measured.
The equivalence point on a titration curve is located at the point where the amount of titrant added is stoichiometrically equivalent to the amount of analyte present in the solution.
Spectrophotometric titration is a technique that combines the principles of spectrophotometry and titration to determine the concentration of a specific analyte in a solution. It involves measuring the absorbance of a sample as a titrant is added in incremental amounts, leading to a titration curve that can be used to calculate the concentration of the analyte.
