The equivalence point reached when the pH reaches it maximum value?
The equivalence point is reached in a titration when the moles of acid are equal to the moles of base added. At the equivalence point, the pH of the solution is at its maximum or minimum value, depending on whether a strong acid or base is used in the titration.
How does the equivalence point differ from the half equivalence point?
Equivalence point is reached when Reactants react at Stoichiometric ratios and reach the Endpoint so that no more of the solution being titrated is found.Eg: Strong base + Strong Acid: HCL+NaOH--> NaCl+H2O1mol of Hcl Requires 1 mol of NaCl,Therefore 3.65 moles of Hcl Requires 3.65Moles of NaOH and equivalence point is reached when that much is added to the acid being titrated for example .Half Eq point is when Half of the Solution being titrated has reacted. It is a point on a titration curve which corresponds to the addition of exactly half of the volume of the titrant needed to reach equivalence point (or end point )Corrected:So, at HALF-WAY Eq. point the pH = pKa, since the actual concentration of ACID is equal to concentration of its conjugate BASE because both are equal to HALF of the original (unknown) acid concentration to be titrated (half left = half formed).
In a titration when the number of moles of hydrogen ions equals the number of moles of hydroxide ions what is said to have happened?
When the number of moles of hydrogen ions equals the number of moles of hydroxide ions in a titration, it means that the solution has reached the equivalence point. At this point, the solution is neutral and the pH is typically around 7, indicating that the acid and base have reacted completely with each other.
If the equivalence point of a titration is 5 what range of pH should the indicator be?
An indicator should have a pKa close to the expected pH at the equivalence point. For a titration with an equivalence point at pH 5, an indicator with a pKa in the range of 4 to 6 would be suitable for visual detection of the endpoint.
What is the relationship of the successive equivalence point volumes in the titration of polyprotic acid?
the end point will be a simple multiple of the first
The equivalence point reached when the pH reaches it maximum value?
The equivalence point is reached in a titration when the moles of acid are equal to the moles of base added. At the equivalence point, the pH of the solution is at its maximum or minimum value, depending on whether a strong acid or base is used in the titration.
What happens to the color of the Fe2 when the equivalence point is reached in a titration?
When the equivalence point is reached in a titration, the color of Fe2 changes because it reacts with the titrant to form a different colored compound.
How to find the equivalence point of a titration?
To find the equivalence point of a titration, you can use an indicator that changes color at the pH of the equivalence point, or use a pH meter to monitor the pH as the titrant is added. The equivalence point is reached when the moles of acid and base are equal, indicating complete neutralization.
How can one determine how to find the equivalence point in a titration experiment?
To find the equivalence point in a titration experiment, one can use an indicator that changes color at the pH of the equivalence point. Alternatively, a pH meter can be used to monitor the pH of the solution during the titration. The equivalence point is reached when the amount of titrant added is stoichiometrically equivalent to the amount of analyte present.
What happens to the color of the FeCl2 when the equivalence point is reached?
FeCI2 is a combination of iron and hydrochloride. This solution starts out as a yellowish green color. When the equivalence point is reach the solution turns to an orange brown color.
Why is it necessary to continue the titration after the equivalence point has been reached?
Continuing the titration after the equivalence point allows for the detection of excess titrant in the solution. This helps to ensure that the exact amount of titrant required to reach the equivalence point has been added. It also allows for a more accurate determination of the endpoint of the titration.
In a titration when does the indicator change color?
when the equivalence point of a titration is achieved.. Added: (More precisely:) The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
How can the concentration of a substance be determined alkalimetrically?
The concentration of a substance can be determined alkalimetrically by titrating it with a known concentration of a base (alkali) until the equivalence point is reached. The volume of the base required to reach the equivalence point is used to calculate the concentration of the substance.
How can one determine the equivalence point in a titration process?
The equivalence point in a titration process can be determined by monitoring the pH level of the solution being titrated. The equivalence point is reached when the pH suddenly changes, indicating that the amount of titrant added is stoichiometrically equivalent to the amount of analyte present. This sudden change in pH is known as the endpoint of the titration.
How does the equivalence point differ from the half equivalence point?
Equivalence point is reached when Reactants react at Stoichiometric ratios and reach the Endpoint so that no more of the solution being titrated is found.Eg: Strong base + Strong Acid: HCL+NaOH--> NaCl+H2O1mol of Hcl Requires 1 mol of NaCl,Therefore 3.65 moles of Hcl Requires 3.65Moles of NaOH and equivalence point is reached when that much is added to the acid being titrated for example .Half Eq point is when Half of the Solution being titrated has reacted.

When the number of moles of hydrogen ions equals the number of moles of hydroxide ions in a titration, it means that the solution has reached the equivalence point. At this point, the solution is neutral and the pH is typically around 7, indicating that the acid and base have reacted completely with each other.
Why the volume increase when you exchange acid-base titration?
The volume increases during an acid-base titration because the titrant (acid or base) is added to the solution being titrated in small increments until the equivalence point is reached, which is when the reaction is complete. This addition of titrant gradually increases the total volume of the solution until the stoichiometric equivalence point is reached.
