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.
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". It signifies the completion of the reaction between the titrant and analyte in the solution being titrated.
What changes color at the endpoint of titration?
The color change at the endpoint of titration is usually due to an indicator that has been added to the solution being titrated. The change in color indicates that the reaction is complete and can help determine the endpoint of the titration.
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.
Why is bromocresol green a suitable indicator in the titration of hydrochloric acid with sodium tetraborate?
Bromocresol green changes color in the pH range of 3.8 to 5.4, which is close to the pH at the endpoint of the titration of hydrochloric acid with sodium tetraborate. This makes it a suitable indicator for this titration as it changes color around the equivalence point.

The point at which the indicator changes color in a titration is called the endpoint.
Changes color at the endpoint of titration?
The color change at the endpoint of a titration is due to the indicator used in the titration process. The indicator changes color based on the pH of the solution, signaling the completion of the reaction between the analyte and titrant. This color change helps determine the equivalence point of the titration.

Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.
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.
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.
What is the purpose of using universal indicator in titration?
Universal indicator is used in titration to indicate the pH of a solution being titrated. It changes color in response to changes in the pH of the solution, helping the observer to determine the endpoint of the titration when the reaction is complete. This allows for a more precise determination of the amount of titrant required to reach the endpoint.
Why there is color change during titration?
Color change during titration occurs when the indicator used changes its form depending on the pH of the solution. Indicators are substances that change color in response to pH changes, allowing us to visually determine the endpoint of the titration. The color change happens because the indicator molecule interconverts between different forms with distinct colors at different pH levels.
What is another example of indicator that used in titration with EDTA?
Another example of an indicator used in a titration with EDTA is Eriochrome Black T. This indicator changes color from red to blue when it forms a complex with metal ions, allowing for the detection of the end point in the titration.
