No, it is never because it has hardly any color (cucumber like), so no good indicator.
The term for the stage in an acid-base titration when the indicator changes color is called the endpoint. It signifies that the stoichiometric equivalence point has been reached, where the acid and base have reacted completely.
The end point in an acid-base titration is the point at which an indicator changes color and signifies that equivalence has been reached between the acid and base being titrated. This is when the amount of acid and base are in stoichiometric proportions.
Phenolphthalein is used as an indicator during the titration of tartaric acid because the pH at which phenolphthalein changes color (around pH 8.2-10) is close to the equivalence point of the titration of tartaric acid with a strong base like NaOH. This makes it a suitable indicator for detecting the endpoint of the titration when the acid has been completely neutralized by the base.
The indicator will change color to indicate when just enough acid has been added to neutralize the sodium hydroxide. For example, phenolphthalein will turn colorless in an acidic solution, indicating that the base has been neutralized.
Phenolphthalein is a suitable indicator for the titration of oxalic acid with sodium hydroxide. It changes color from colorless to pink at the endpoint of the titration when the acid has been completely neutralized.
The endpoint of an acid-base titration is the point at which the indicator changes color or the pH meter reads a significant change in pH, indicating that the reaction between the acid and base is complete. This point signifies that the equivalence point has been reached, where the moles of acid and base have reacted in stoichiometric proportions.
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
Adding a few drops of indicator helps to visually identify the endpoint of the titration, which is the point at which the reaction is complete. The indicator changes color at a specific pH, indicating that the acid and base have been completely neutralized. This helps the titrator know when to stop adding the titrant.
A color change in an acid-base titration indicates the endpoint of the reaction, where the amount of acid or base has been completely neutralized. This change is often detected using a pH indicator that changes color based on the pH of the solution. The color change helps in determining the equivalence point of the titration.
An indicator changes color at a specific pH range. To determine the endpoint of a neutralization reaction, an indicator that changes color near the neutral pH of 7 would be used. The reaction is stopped when the indicator changes color, indicating that the acid and base have been neutralized.
Phenolphthalein is commonly used as an indicator in the titration of hydrochloric acid (HCl) with sodium hydroxide (NaOH). Phenolphthalein changes color from colorless to pink at the endpoint of the titration when all the acid has been neutralized by the base.
One way to neutralize acid is by adding a base, which will react with the acid to form water and a salt. This reaction will decrease the acidity of the solution by balancing the concentrations of hydrogen ions and hydroxide ions. Additionally, using a pH indicator can help determine when the acid has been fully neutralized.
