What is the name of the point at which wavelength independent pH and absorbance?

The isosbestic point is the name of the point at which a system displays wavelength-independent pH and absorbance.


When Isosbestic point observed?

If the spectra of two compounds with a constant total concentration cross at any wavelength, all mixtures with the same total concentration will go through that same point. The appearance of isobestic points in a chemical reaction is good evidence that we are observing one main species being converted to one other major species.


Difference between spectrophotometry and differential spectrophotometry?

Differential spectrophotometry is a spectrophotometric analytical technique in which a solution of the sample's major component is placed in the reference cell and the recorded spectrum represents the difference between the sample cell and the reference cell...basically it uses major component of system as reference and NOT solvent ..for example if a enzyme ligand system is to be assayed ..enzyme + solvent is reference and enzyme + ligand + solvent is test sample..its for quantitative detection.

What is the significance of the isosbestic point in a pH titration curve?

The isosbestic point in a pH titration curve is significant because it represents the point where the concentrations of the acid and its conjugate base are equal. This point indicates the equivalence point of the titration, where the amount of acid added is stoichiometrically equivalent to the amount of base present. It helps in determining the unknown concentration of the acid or base being titrated.


What does it mean if there is no isosbestic point on an asborbance spectra?

Nothing! -- Not at all!The Absence of an Isosbestic Point on a couple of Spectra on the same Plot doesn't mean anything at all!Without any other very relevant Information absolutely no Statement of any kind is possible!

What is the definition of Spectrophotometry?

The term "Spectrophotometry" refers to an instrument that is often used to determine the intensity of the various wavelengths in a spectrum of light. This tool is a part of analytical chemistry.


What is difference between photospectrometry and spectrophotometry?

Photospectrometry measures how light interacts with matter to analyze the composition and properties of substances, while spectrophotometry measures the intensity of light absorbed or transmitted by a substance to determine its concentration within a sample. In essence, photospectrometry focuses on the interaction of light and matter, while spectrophotometry focuses on the concentration of a substance.


What is the relationship between wavelength and absorbance in a spectrophotometry experiment?

In a spectrophotometry experiment, there is an inverse relationship between wavelength and absorbance. This means that as the wavelength of light increases, the absorbance decreases, and vice versa.


What does a high absorbance indicate in a spectrophotometry analysis?

A high absorbance in a spectrophotometry analysis indicates that a substance strongly absorbs light at a specific wavelength, which can be used to determine the concentration of the substance in the sample.


What does a high absorbance indicate in spectrophotometry?

A high absorbance in spectrophotometry indicates that a substance strongly absorbs light at a specific wavelength, suggesting a high concentration of that substance in the sample being analyzed.
