Why the solution turn to pink at the end of thr titration?
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.
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.
What color will a solution be at the equivalence point of titration?
The color of a solution at the equivalence point of a titration depends on the type of indicator used. The indicator changes color at a specific pH value, signaling the completion of the reaction. Common indicators like phenolphthalein turn pink at the equivalence point of an acid-base titration.
When does phenolphthalein turn pink?
Phenolphthalein turns pink in a basic solution with a pH greater than 8.2. It is commonly used as an acid-base indicator to visually show the endpoint of a titration when the pH of the solution changes.
Why is nitrobenzene added to titration mixture?
Nitrobenzene is added to the titration mixture as a color indicator for the endpoint of the titration. It imparts a pink color to the solution which disappears when the reaction is complete. This helps to visually determine when the equivalent point has been reached.
Why did the solution turn into light pink at the end of the titration?
The pH was changed.
Why the solution turn to pink at the end of thr titration?
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 indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
The indicator methyl orange can be used in the titration of sodium carbonate solution against hydrochloric acid to give a complete neutralization. At the endpoint, when all the carbonate ions have reacted to form bicarbonate ions, the solution will turn from yellow to pink.
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.
Which indicator is used in titration of naoh and h2so4?
Phenolphthalein is commonly used as an indicator in the titration of NaOH and H2SO4. It changes color from colorless to pink as the solution reaches a specific pH range, signaling the endpoint of the titration.
Phenolphthalein solution is used as an indicator of acids and bases. If added to an ammonia-based solution of window cleaner we would expect the solution to turn?
Phenolphthalein will turn pink or magenta in basic solutions and remain colorless in acidic solutions. Therefore, if added to an ammonia-based solution of window cleaner, which is basic, we would expect the solution to turn pink or magenta.
