Types of conductometric titration?
Some types of conductometric titrations include acid-base titrations, redox titrations, and precipitation titrations. Conductometric titration involves measuring the change in electrical conductivity as reactants are titrated against each other until an equivalence point is reached.
What are the differences between conductometric and volumetric titrations?
Conductometric titrations measure the change in electrical conductivity during a titration, while volumetric titrations measure the volume of titrant needed to reach the equivalence point. Conductometric titrations are more sensitive to small changes in concentration, while volumetric titrations are more straightforward to perform and interpret.
What are the type of conductometric titration?
The types of conductometric titrations include strong acid-strong base titrations, weak acid-strong base titrations, weak base-strong acid titrations, and precipitation titrations. Conductometric titrations measure the change in electrical conductivity of a solution as a titrant is added, allowing for the determination of the endpoint of the reaction.
Why is it necessary to dilute the titrand in conductometric titrations?
Diluting the titrand in conductometric titrations helps to ensure a more linear relationship between the conductivity and the concentration of the analyte. This can improve the accuracy and precision of the titration results. Additionally, dilution can prevent issues such as excessive conductivity that could lead to errors in the titration endpoint determination.
What is the difference between conductometric and volumetric titrations?
Coductometric titration: is based on the suddenly change of the conductivity at the equivalence point.Volumetric titration: the volume of a standardized titrant is measured at the eqivalence point.

Why oxalic acid is used in conductometric titrations?
Oxalic acid is used in conductometric titrations because it is a strong electrolyte that dissociates completely in solution, leading to a sharp increase in conductivity at the equivalence point. This makes it easier to accurately determine the endpoint of the titration.
Why AC is used at high frequncy in conductometric titration?
AC is used at high frequencies in conductometric titration to minimize electrolysis effects and polarization at the electrode surface. At high frequencies, these effects are reduced, resulting in better sensitivity and accuracy of the titration measurements. Additionally, using high frequency AC helps to maintain a constant electrolyte concentration and minimize errors in the conductometric titration process.
Why is it recommended to carryout iodometric titrations as quick as possible?
Iodometric titrations involve the titration of iodine with a reducing agent. Iodine is volatile and can escape into the air, which can lead to errors in the titration results. To minimize these errors, it is recommended to carry out iodometric titrations as quickly as possible to prevent the loss of iodine and ensure accurate results.
Why do conductance increases after the end point in conductometric titrations?
Conductance can increase after the end point in conductometric titrations due to the presence of excess titrant in the solution, leading to higher conductivity. This excess titrant can contribute to the conductance of the solution and cause an increase in measured conductance. Factors such as incomplete reaction or side reactions can also contribute to the increase in conductance post-end point.
Why you use only platinum electrodes in conductometric titrations?
Platinum electrodes are commonly used in conductometric titrations because they are inert, meaning they do not react with the solutions being tested, ensuring accurate measurements. In addition, platinum electrodes have good electrical conductivity and stability, making them reliable for consistent and precise titration results.
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.
