To determine the molecular weight from a titration curve, one can identify the equivalence point on the curve where the amount of titrant added is equal to the amount of analyte present. By knowing the molarity of the titrant and the volume added at the equivalence point, one can calculate the moles of analyte. Then, by dividing the mass of the analyte by the moles, the molecular weight can be determined.

How will determine Molecular weight by Landsberger method?
we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula M2=(KBW2)*1000/T'W1 where M2=molecular mass Kb=ebullioscopic constant or molal boiling point constant W2=mass of solute W1=mass of solvent T'=change in temprature
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.
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.
How can one determine the half equivalence point from a titration curve?
The half equivalence point on a titration curve can be determined by finding the point where half of the acid or base has reacted with the titrant. This is typically located at the midpoint of the vertical section of the curve, where the pH changes most rapidly.
How can one determine the half equivalence point on a titration curve?
The half equivalence point on a titration curve can be determined by finding the point where half of the acid or base has reacted with the titrant. This is typically located at the midpoint of the vertical region of the curve, where the pH changes most rapidly.

How do you calculate molecular weight in electrophoresis?
To calculate the molecular weight of a protein in electrophoresis, you would use a standard curve generated with protein standards of known molecular weights run on the same gel. By plotting the migration distance of the standard proteins against their known molecular weights, you can then determine the molecular weight of your protein of interest based on its migration distance on the gel in comparison to the standard curve.

How can one determine the equivalence point on a titration curve?
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.
What are the primary factors influence shape of a complexometric titration curve?
The primary factors that influence the shape of a complexometric titration curve include the stoichiometry of the metal-ligand complex formation, the equilibrium constants associated with complex formation, and the pH of the solution. These factors determine the composition and stability of the complexes formed during the titration, which in turn affect the shape of the curve.
How can one determine the acid dissociation constant (Ka) from a titration curve?
To determine the acid dissociation constant (Ka) from a titration curve, one can identify the equivalence point on the curve where the amount of acid equals the amount of base added. By analyzing the pH at the equivalence point and using the initial concentration of the acid, the Ka can be calculated using the Henderson-Hasselbalch equation.
What is spectrophotometric titration?
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.
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.
How do you determine ka from a titration curve?
Assuming you know how to find the equivalence point on the titration curve, and assuming it is not [strong acid/strong base] or [weak acid/weak base], all you need to do is find the half equivalence point, which gives you the pKa of the first solution. Then to get the Ka, you go 10-pKa .
