A colorimetric endpoint refers to a specific point in a chemical reaction or assay where a distinct color change indicates the completion of the reaction or the presence of a particular substance. This change is often measured using a colorimeter, which quantifies the intensity of color produced, allowing for the determination of concentration levels of analytes in a sample. Colorimetric endpoints are commonly used in various applications, including biochemical assays, environmental testing, and food analysis.
What else can I help you with?
Point at the end of a line segment or ray?
an end point
Does an endpoint go on forever in geometry?
the part with the end point does not, it stops at the end point. But if there is only one end point on a line, the other end does go on forever
Does ray have a one end point?
A ray has only one end point.
What is the end point of a ray called?
point
Does a line segment have only one end point?
No, it has two. A ray has one end point.
What is the difference between equivalent point and end point in analytical chemistry?
The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte. The end point is the point in a titration when a physical change occurring immediate after the equivalence point
What has the author Jaroslav Bartos written?

A point at an end of a segment or a starting point of a ray?
end point
Why is the choice of the colorimetric indicator in an acid-base titration important?
The choice of colorimetric indicator in an acid-base titration is crucial because it must change color at the equivalence point, where the moles of acid and base are stoichiometrically equal. The indicator should have a pH range close to the pH at the equivalence point to ensure accurate endpoint detection. Using the right indicator helps to determine the endpoint precisely and enhances the accuracy of the titration results.
What is colorimetric titration?
The term is sometimes applied titrations where the end point is determined by a color change- e.g. using ssy methyl orange. Sometimes the term is used when a colorimeter is used- the absorption at a particular frequency of light is used to determine the concentration- (Beers Law)
What is stoichiometric end point?
when stoichiometric amounts of the titrant and the analyte have completely reacted. this differs from an endpoint which is when a secondary indicator's color change takes place. :) hope that helps
What colorimetric pH indicator should you use for ammonia and hydrochloric acid titration?
Since the titration is between a strong acid and a weak base, methylorange should be suitable as the equivalence point is around pH 5. The K of the indicator should be equal to the pH at the end point. Methyl orange is that indicator
What can you use Sudan lll colorimetric test for?
to test for the presence of lipids.
The point in a titration at which the indicator changes is called the?
End point...
How do you determine the colorimetric estimation of unknown copper sulphate concentration in solution?
To determine the colorimetric estimation of unknown copper sulfate concentration in solution, you can use a colorimetric method such as a complexation reaction with a specific reagent that forms a colored complex with copper ions. By measuring the absorbance of this colored complex at a specific wavelength using a colorimeter, you can correlate the absorbance values to known copper sulfate concentrations to determine the concentration of the unknown solution. Calibration curve plotting absorbance against known concentrations is commonly used in colorimetric estimations.
Point at the end of a line segment or ray?
an end point
How do you use calorimetric in a sentence?
Got this off another site but...Colorimetric equipment is similar to that used in spectrophotometry <-i dont even know what that word means You could also say...Colorimetric is a word that is hard to use in a sentence...lol
