What is the pH at the stoichiometric point of the titration of 25.0 mL of aqueous hypochlorous acid with 0.20 M KOH aq?
The stoichiometric point of the titration of hypochlorous acid (HOCl) with KOH occurs when all the acid has reacted with the base to form the salt, potassium hypochlorite (KClO). At this point, the pH is determined by the hydrolysis of the resulting salt, which forms hypochlorite ions (ClO-) and hydroxide ions (OH-). The pH at the stoichiometric point is determined by the concentration of these ions and can be calculated using the equilibrium constant for the hydrolysis reaction.
The end point of a titration indicates the?
The end point of a titration indicates the point at which the reaction has reached stoichiometric equivalence between the titrant and analyte. This is typically signaled by a noticeable change in a physical property, such as a color change in an indicator or a change in pH.
What is meant by the end point during a titration?
The end point in a titration is when the indicator used changes color, signaling that the reaction is complete. It indicates that the stoichiometric amount of titrant has been added to react completely with the analyte.
What is the equivalence or stoichiometric point?
At the stoichiometric point of a titration, the total amount (in moles) of OH- ions that have been added as a titrant is exactly equal to the amount of H3O+ ions initially present in the beaker.The measured pH of at the stoichiometric point of a strong acid-strong base titration is expected to be that of pure water i.e. pH = 7. In practice, attainment of the stoichiometric point will be marked by sudden sharp rise in pH from a value significantly below 7 to a value significantly above 7.
What is the term for the stage in an acid-base titration when the indicator changes color?
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.

What is stoichiometric end point?
when stoichiometric amounts of the titrant and the analyte have completely reacted. this differs from an endpoint which is when a secondary indicator's color change takes place. :) hope that helps
Which is the end point in acid base titration?
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.
What is true about the amounts of H and OH at the stoichiometric point in a titration of a strong acid with a strong base?
At the stoichiometric point in a titration of a strong acid with a strong base, the amounts of H+ and OH- ions are equal. This results in a neutral solution as the acid and base have completely reacted to form water.
Is the stoichiometric point for a weak acid strong base titration to be greater or less than 7?
The stoichiometric point for a weak acid-strong base titration is generally greater than pH 7 because the titration involves adding a strong base (like NaOH) to a weak acid solution. At the stoichiometric point, all of the weak acid has been neutralized by the strong base, resulting in the formation of the conjugate base and water, which makes the solution slightly basic.
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.
The point in a titration at which the indicator changes is called the?
End point...
What is meant the endpoint of an acid-base titration?
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.
