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.
If we plot the pM (M= concentration of metal ion in the analyte) against the volume of titrant the titration curve takes the sigmoidal shape, plateau in the first part, sharp rise around the equivalence point and then again flat.
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.

The buffer region in a titration curve is significant because it shows where the solution is most resistant to changes in pH. This is important because it helps maintain the stability of the solution and allows for accurate determination of the equivalence point in the titration process.
The independent variable in a titration is the volume of titrant added to the analyte solution. It is controlled by the person conducting the experiment and is typically plotted on the x-axis of a titration curve.
To calculate the pKa from a titration curve, identify the point on the curve where the concentration of the acid and its conjugate base are equal. This is the half-equivalence point. The pH at this point is equal to the pKa of the acid.
The approximate pH of the equivalence point in a titration pH curve is around 7 for a strong acid-strong base titration. This is because at the equivalence point, the moles of acid are equal to the moles of base, resulting in a neutral solution.
To determine the equivalence point on a titration curve in Excel, you can identify the point where the slope of the curve is steepest. This is where the concentration of the titrant is equal to the concentration of the analyte being titrated. You can use Excel to plot the titration data and calculate the derivative of the curve to find the point of maximum slope, which corresponds to the equivalence point.
The equivalence point on a titration curve can be determined by finding the point where the amount of titrant added is equal to the amount of analyte present in the solution. This is typically indicated by a sharp change in pH or a significant change in color of the indicator used in the titration.
