In a titration the pipette is used to transfer 25 cm3 (usually to ±0.05 cm3) of a solution into a conical flask. Another solution that reacts with the solution in the conical flask is carefully added from a burette until it has all exactly reacted. This is called the end point of the titration (or equivalence point of the reaction). There needs to be a way of knowing when the end point is reached. An indicator may be needed. Often a titration is repeated until successive titres are within 0.1 cm3.
What else can I help you with?
Why is no indicator needed in redox titration experiment?
No indicator is needed in redox titration because the endpoint of the titration is determined by a change in the appearance of the titrand. This change can be detected visually, such as a color change, indicating the completion of the reaction without the need for an indicator.
Is the indicator generally added to the titrant or the analyte in a titration?
Analyte is the indicator that is generally added in titration.
What is the name for the point at which the indicator changes color in a titration?
The point at which the indicator changes color in a titration is called the endpoint.
Why is the indicator not added to the titration flask at the begging of the iodomettic titration?
Adding the indicator at the beginning of the iodometric titration can react with the iodine present, which can lead to errors in the titration results. By adding the indicator after most of the iodine has reacted, it ensures that the endpoint is more accurate and reliable.
Why titration not require an external indicator?
Titration does not always require an external indicator because some reactions involved in titration produce a noticeable color change, known as a self-indicating reaction. This color change signals the endpoint of the titration without the need for an external indicator. Examples include the reaction between acid and base or with certain metal ions.

How half titration could be done using only an indicator solution without PH?
In a half titration, you can use an indicator solution without needing to measure pH by adding the indicator directly to the reacting mixture and observing the color change. This can help you identify the endpoint of the titration, where half of the analyte has been neutralized. The color change will indicate the completion of the reaction, signaling that half of the titrant has been added.

How you select that which indicator should be used in any titration?
The selection of an indicator for a titration is based on the pH range over which the titration will occur. The indicator should have a color change that aligns with the pH at the equivalence point of the titration. Choosing an indicator with a pH range that encompasses the equivalence point will ensure accurate endpoint detection.
Why is important that the indicator is present in the solution during the course of titration?
the reason why a indicator is important in some titration is to show a change in the solution. for example as a solution runs from acidic to basic the indicator may turn a different color. but this is the reason why it is important inmost experiments.
What is double indicator titration?
Double indicator titration is a type of titration method that involves the use of two different indicators to determine the endpoint of the reaction. The first indicator changes color near the starting pH of the titration, while the second indicator undergoes a distinct color change at or near the endpoint of the titration. This technique is commonly used in complexometric titrations to determine the concentrations of metal ions in a solution.
Describe a method to visually detect the end point of a titration without the use of instruments?
The method used most often in chemistry labs is by use of a pH indicator in the sample being titrated. When you reach the titration point, the indicator will change colors, demonstrating the end point of the titration.
