What is the stoichiometric point of a titration called?
The stoichiometric point of a titration is called the equivalence point. At this point, the moles of acid and base have reacted in exact stoichiometric proportions, resulting in complete neutralization.
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.
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.
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.
Conductometric titration of a strong acid with a strong base?
In conductometric titration of a strong acid with a strong base, as the base is added to the acid solution, the conductivity of the solution increases due to the formation of ions. The inflection point of the titration curve corresponds to the stoichiometric equivalence point, where all the acid has been neutralized by the base. The conductivity then remains constant beyond this point, indicating excess of the base.

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 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 factors influence the pH at the equivalence point in a strong-strong titration?
The factors that influence the pH at the equivalence point in a strong-strong titration are the strength of the acid and base being titrated, the concentration of the acid and base, and the volume of the acid and base used in the titration.
How would the pH of the equivalence point for standard solution titration differ from a strong acid-strong base titration?
The pH at the equivalence point of a strong acid-strong base titration would be 7, as the solution is neutralized. In contrast, the pH at the equivalence point for a standard solution titration would depend on the nature of the reaction and the strengths of the acids and bases involved.
A titration of an acid and base to the equivalence point results in a noticeably acidic solution It is likely this titration involves?
a weak acid and strong base. At the equivalence point of a titration between a weak acid and a strong base, the resulting solution will have a pH greater than 7, indicating a basic solution. For the solution to be noticeably acidic at the equivalence point, it would suggest an excess of the weak acid after the reaction, which means that the acid is likely weak and not completely neutralized by the strong base.
