The solution turns pink at the end of the titration when an indicator like phenolphthalein is used to detect the endpoint. In this case, phenolphthalein turns pink in basic solutions, indicating that the acid has been neutralized and the endpoint of the titration has been reached.
What else can I help you with?
Why did the solution turn to pink at the end of the titration?
The pink color at the end of the titration could be due to the indicator phenolphthalein, which turns pink in basic solutions. This indicates that the solution has reached its endpoint and is slightly basic.
Why did the solution turn to pink at the of the titration?
because the solution react with sulphuric acid. other than that, the end point is indicated.
Why pink colour appears at the end point in permanganometric titration?
The pink color at the end point of a permanganometric titration occurs due to the formation of MnO4- ions. These ions impart the pink color to the solution when they are in excess, indicating the end of the reaction between the analyte and the titrant.
Why did the redox titration turn to light pink at the end of the titration?
The light pink color at the end of a redox titration is often due to the formation of a complex between the titrant and the analyte. This complex can have a color that is different from the initial colors of the reactants, resulting in the observed color change.
Why did the solution turn to pink at the end point of the titration?
The pink color indicates that the pH has reached a specified endpoint in the titration process. In acid-base titrations, a pink color is often associated with the addition of an indicator such as phenolphthalein which changes color at a specific pH, typically around pH 8.2-10. This color change signals the completion of the reaction between the acid and base being titrated.
Why did the solution turn into light pink at the end of the titration?
The pH was changed.
Why did the solution turn to pink at the end of the titration?
The pink color at the end of the titration could be due to the indicator phenolphthalein, which turns pink in basic solutions. This indicates that the solution has reached its endpoint and is slightly basic.
Why did the solution turn to pink at the of the titration?
because the solution react with sulphuric acid. other than that, the end point is indicated.
Why pink colour appears at the end point in permanganometric titration?
The pink color at the end point of a permanganometric titration occurs due to the formation of MnO4- ions. These ions impart the pink color to the solution when they are in excess, indicating the end of the reaction between the analyte and the titrant.

The light pink color at the end of a redox titration is often due to the formation of a complex between the titrant and the analyte. This complex can have a color that is different from the initial colors of the reactants, resulting in the observed color change.

In acid-base titrations, a pink color is often associated with the addition of an indicator such as phenolphthalein which changes color at a specific pH, typically around pH 8.2-10. This color change signals the completion of the reaction between the acid and base being titrated.
What color indicates that a titration using phenolphthalein has reached the end point?
The color pink indicates that a titration using phenolphthalein has reached the end point.
Why starch is added towards the end of titration?
Starch is added towards the end of titration as an indicator to help visualize the endpoint. When the starch is added, the solution will turn blue-black in the presence of excess iodine, indicating that the reaction is complete. This color change helps in accurately determining the endpoint of the titration.
What is a solution of a known concentration used in the process of titration?
In titration, a solution of a known concentration is called the standard solution or titrant. It is used to react with the analyte solution of unknown concentration to determine the concentration of the analyte. The titrant is added to the analyte solution until the equivalence point is reached, signaling the end of the titration.
How does starch solution indicate the end point of the titration?
Starch solution is added near the endpoint of the titration as an indicator. When the solution changes from blue to colorless, it signals that the titration is complete. This is because the iodine in the starch-iodine complex will no longer react with the analyte, leading to the color change.
Why no use indicator in the standardizing potassium permanganate titration?
In the standardization of potassium permanganate titration, an indicator is not used because the titration is self-indicating. This means the solution being titrated changes color at the end point, so an additional indicator is not necessary. It is important to carefully observe the color change to ensure accurate titration results.
What is conductometric tiration?
Conductometric titration is a method of titration where the end point is determined by measuring the change in electrical conductivity of the solution being titrated. It is commonly used to determine the concentration of ions in a solution.
