Which methods can be used to detect end point in titration?
Which methods can be used to detect end point in titration?
Methods for determining the end point include (1) detecting a sudden change in the voltage or current between a pair of electrodes, (2) observing an indicator color change, and (3) monitoring absorption of light by the titrant or analyte and/or product.
What is an endpoint titration?
end point: the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.
What are the titration methods?
Titrimetric methods have been developed using acid–base, complexation, redox, and precipitation reactions. Acid–base titrations use a strong acid or a strong base as a titrant. The most common titrant for a complexation titration is EDTA.
How do you find the end point?
When the titration reaction goes to completion, and if the effects of dilution over the course of a titration are ignored or corrected for, the analyte concentration will decrease linearly. The X-intercept on a plot with moles of analyte on the Y-axis and volume of titrant added on the X-axis will be the endpoint.
Which instrument is used to detection of endpoint?
In general, phenolphthalein is used as an indicator for the titration of weak acid against strong base.
What is meant by an end point?
Definition of end point 1 : a point marking the completion of a process or stage of a process especially : a point in a titration at which a definite effect (such as a color change) is observed.
How many types of titration do you know?
Introduction to Titration and Types of Titration First of all, titration is an important part of the study of chemistry. Furthermore, there are four important types of titration. It is a must for physical chemistry laboratory experiments.
How many types of complexometric titration are there?
Direct titration: the cations are titrated directly with standard solution EDTA using eriochrome black T as the indicator. Back titration: a known excess of standard solution EDTA is added to the solution containing the analyte.
What is the meaning end point?
What is the indicator endpoint?
The point at which the indicator changes color is called the endpoint. So the addition of an indicator to the analyte solution helps us to visually spot the equivalence point in an acid-base titration. Endpoint: refers to the point at which the indicator changes color in an acid-base titration.
What is another name for endpoint?

What happens at the end point in a titration?
The end point typically comes straight after the equivalence point, which is when the moles of a standard solution (titrant) equal the moles of a solution of unknown concentration (analyte), i.e., the ideal point for the completion of titration. In a perfect titration, the end point and equivalence are identical.
What is the purpose of a titration end point?
Endpoint And Equivalence Point Titration measures the concentration of an unknown solution that reacts with a solution of known concentration. The process is often used to check the purity of synthesized chemical compounds such as pharmaceuticals. The ideal point for completion of titration is known as the equivalence point.
What is meant by the end point during a titration?
Endpoint is the point in the titration where the indicator changes its color.
What is the endpoint of a titration?
An endpoint is indicated by some form of indicator at the end of a titration. An equivalence point is when the moles of a standard solution (titrant) equal the moles of a solution of unknown concentration (analyte).
