Why is the point in the titration when neutralization occurs called the equivalence point?
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.
What else can I help you with?
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.
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.
A measure of acidity is called neutralization?
Acidity is measured by pH. Acids have a pH below 7.0 (pH of 7.0 being neutral). The lower the pH, the more acidic the substance. When acids and bases are mixed, neutralization occurs.
When neutralization occurs what two substances are formed?
When neutralization occurs, an acid and a base react to form a salt and water.
When has the titration reached its equivalence point?
The equivalence point in a titration is reached when the amount of titrant added is stoichiometrically equivalent to the amount of analyte present in the solution. This is determined by the reaction's balanced equation, where the moles of acid equal the moles of base, or vice versa. At this point, a noticeable change in a property, such as pH, occurs, often indicated by a color change if an indicator is used. In a more precise setting, it can be detected using pH meters or other analytical techniques.
