Consider the titration of 30.0 ml of 0.030 M NH3 with 0.025 M HCl the equivalence point is reached when 36 ml of HCl titrant is added what is the pH at the equivalence point?
pH = 5.56 at 36.0 ml(equivalence point)
When is neutralization reached in titration?
Neutralization occurs at the "equivalence point," where the moles of your acid and your base are the same. A chemical indicator tells you when this point is reached, and changes color appropriately.
Why you useindicator in titration?
Most solutions used in titrations are colorless, therefore you cannot really estimate the equivalence point (the volume of added titrant that causes a stoechiometric reaction). However, slight variations in other factors such as acidity (pH) can be detected by means of an indicator, which will change color accordingly. This will notify you when you have reached the equivalence point.
Why is titration repeated without indicator?
In a titration the pipette is used to transfer 25 cm3 (usually to ±0.05 cm3) of a solution into a conical flask. Another solution that reacts with the solution in the conical flask is carefully added from a burette until it has all exactly reacted. This is called the end point of the titration (or equivalence point of the reaction). There needs to be a way of knowing when the end point is reached. An indicator may be needed. Often a titration is repeated until successive titres are within 0.1 cm3.
Why is titration repeated 3 times?
to find out when you have reached the end point

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?
the equivalence point has been reached
The equivalence point reached when the pH reaches it maximum value?
No. The equivalence point is reached when the moles of titrant equals the moles of analyte.

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).
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.
How is an indicator used to determine the pH of a solution?
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!
What is an endpoint?
An endpoint is what happens when something has reached completion. It is also the final stage of a given process.
