The titration curve of phosphoric acid and sodium hydroxide shows the pH changes as the two substances are mixed in a controlled manner. At the start, the pH is low due to the acidic nature of phosphoric acid. As sodium hydroxide is added, the pH gradually increases until it reaches a plateau at each equivalence point, where the acid and base have completely reacted. The curve typically shows three distinct equivalence points corresponding to the three acidic hydrogen atoms in phosphoric acid.

What is the example of titration curve in monoprotic acid?
An example of a titration curve for a monoprotic acid, such as hydrochloric acid with sodium hydroxide, would show a sharp equivalence point. Initially, the pH is low due to the presence of the strong acid, then rises gradually as the base is added until it sharply increases at the equivalence point, showing a steep vertical rise.
What is nature of titration curve obtained in titration of hcl against naoh?
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.
What is the product of titration?
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.
How can one calculate the pKa from 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.
Where is the equivalence point located on a titration curve?
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.

How do you determine the pka of oxalic acid?
To determine the pKa of oxalic acid, you can perform a titration experiment. By titrating a solution of oxalic acid with a strong base such as sodium hydroxide (NaOH) and monitoring the pH changes, you can identify the point where the acid is half-neutralized and calculate the pKa value. This is typically done using a pH meter or pH indicator to track the changes in acidity as the titration progresses.
Where is the equivalence point located on a titration curve?
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.
How can one determine the equivalence point on a titration curve in Excel?
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.
What is the Shape of titration curve for complexometric titration?
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.
How can one determine the pKa from a titration curve?
To determine the pKa from a titration curve, identify the point on the curve where the pH is equal to the pKa value. This point represents the halfway point of the buffering region, where the concentration of the acid and its conjugate base are equal.
What is the approximate pH of the equivalence point in the titration pH curve?
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.
What is the significance of the buffer region in a titration curve?
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.
