What else can I help you with?
In an acid-base titration equivalent quantities of hydronium ions and hydroxide ions are present a. at the beginning point. c. at the endpoint. b. at the midpoint. d. throughout the titration.?
At the endpoint.
What is the scout titration?
The scout titration is a preliminary titration carried out to estimate the approximate endpoint in a titration experiment before performing the actual titration. It helps in determining the approximate volume of titrant required for the main titration to avoid overshooting the endpoint.
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 endpoint in titration?
The endpoint of a titration is when the indicator first changes in appearance, or when an instrument first gives a reading which indicates that the titration is finished. The endpoint is always slightly after the equivalence point.
What is the difference between rough and accurate titration?
Rough titration is an initial estimation to determine the approximate endpoint of a titration, while accurate titration involves fine adjustments to precisely determine the endpoint. Rough titration is typically done quickly and gives a ballpark figure, whereas accurate titration is more meticulous and provides a precise measurement.

How is the endpoint of a titration between H3PO4 and NaOH determined?
The endpoint of a titration between H3PO4 (phosphoric acid) and NaOH (sodium hydroxide) is determined by using an indicator that changes color when the reaction is complete. This indicator helps to visually identify when the acid and base have reacted in the correct proportions, indicating the endpoint of the titration.
When equivalent amounts of H and OH have reacted in a 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.
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.
What is the error that occur in the titration?
Common errors in titration include incomplete reaction, improper mixing of reagents, inaccurate measurements, presence of impurities in the sample, and endpoint detection errors (e.g., overshooting the endpoint). These errors can result in inaccurate titration results.
How does the equivalence point differ from the endpoint of a titration?
The equivalence point in a titration is the point at which the moles of titrant added are stoichiometrically equivalent to the moles of analyte present. The endpoint is when an indicator used in the titration changes color, signaling the completion of the reaction. The equivalence point is a calculated value based on the stoichiometry of the reaction, while the endpoint is detected visually.
When equivalent amounts of h plus and OH- have reacted in titration?
