Why is the point in the titration when neutralization occurs called the equivalence point?
Wiki User
∙ 11y ago
The equivalence point is where the moles of acid and base in a reaction are present in stoichiometrically equal amounts, resulting in complete neutralization. It is called the equivalence point because the reactants are equivalent in terms of their chemical equivalence at this stage of the titration process.

When is neutralization reached in titration?
Neutralization is reached in a titration when the acid and base have reacted completely with each other, resulting in a solution that is neither acidic nor basic but neutral. This is indicated by a stable pH value close to 7 and can be confirmed by using an acid-base indicator or a pH meter.
Where is the buffer region in a titration curve for the titration of a weak acid with a strong base?
The buffer region in a titration curve for the titration of a weak acid with a strong base is typically located at the vicinity of the equivalence point. This region occurs when the weak acid has been partially neutralized by the strong base, resulting in the presence of a buffer solution that resists large changes in pH.
Why phenolphthalein cannot be used as an indicator for titrating a weak base against a strong acid?
Phenolphthalein is not suitable for this titration because its color change occurs over a pH range that is beyond the equivalence point of the weak base and strong acid titration. At the equivalence point of this titration, the solution is acidic, which is below phenolphthalein's color change pH range. This can lead to inaccurate results and difficulty in determining the endpoint of the titration.
What is Over titration?
Over titration occurs when too much titrant is added during a titration process, leading to incorrect results. This can be due to human error, poor technique, or using an incorrect concentration of titrant. To avoid over titration, it is important to carefully monitor the reaction and follow the titration procedure accurately.
Why potentiometric titration curves are s-shaped?
Potentiometric titration curves are s-shaped due to the buffering capacity of the solution. At the beginning of the titration, minimal change in pH occurs as the solution acts as a buffer, resisting pH changes. Once the buffer region is overcome, the titration curve becomes steeper as the solution approaches the equivalence point.

What reaction occurs when an acid and a base mix and react?
The reaction is called neutralization.
What is the principle of conductometric titration?
The principle of conductometric titration involves measuring the change in electrical conductivity of a solution as a titrant is added to a sample solution. This change in conductivity occurs due to the formation or consumption of ions during the titration process, which can be used to determine the endpoint of the titration. Conductometric titration is commonly used to determine the concentration of ions in a solution or to identify the equivalence point in acid-base titrations.
What is the aim of a thermometric titration?
The aim of a thermometric titration is to measure the heat change that occurs during a titration reaction. This can be used to determine the endpoint of the titration, as it corresponds to the point of maximum or minimum heat change. Thermometric titrations are useful for studying reactions that do not produce a visible change in color or involve weakly-colored solutions.
What is it called when properties of acids and bases are lost?
When properties of acids and bases are lost, it is known as neutralization. Neutralization occurs when an acid and a base react to form water and a salt, resulting in a solution that is no longer acidic or basic.
When neutralization occurs what two substances are formed?
When neutralization occurs, an acid and a base react to form a salt and water.
A measure of acidity is called neutralization?
Actually, a measure of acidity is called pH. Neutralization is the chemical reaction that occurs when an acid and a base react to form water and a salt.
What is neutralization in chemistry?
Neutralization is a chemical reaction that occurs when an acid reacts with a base to produce water and a salt. The reaction involves the transfer of protons from the acid to the base, resulting in the formation of water molecules. This process helps in neutralizing the acidity or basicity of the solution.
