FAQs on Conductometric Titrations Video Lecture - Inorganic Chemistry

1. What is a conductometric titration?
Ans. A conductometric titration is a method used in analytical chemistry to determine the concentration of a substance in a solution by measuring its electrical conductivity. It involves adding a titrant solution of known concentration to the analyte solution until a chemical reaction occurs, resulting in a change in conductivity. By monitoring this change, the concentration of the analyte can be determined.
2. How does a conductometric titration work?
Ans. In a conductometric titration, the analyte solution and the titrant solution are mixed together. Initially, the conductivity of the analyte solution is measured. As the titrant is gradually added, it reacts with the analyte, causing a change in conductivity. The conductivity is continuously monitored, typically using a conductometer, until a sudden or gradual change is observed. This change indicates the completion of the reaction and allows for the determination of the analyte concentration.
3. What are the advantages of conductometric titrations?
Ans. Conductometric titrations have several advantages. Firstly, they are highly sensitive and can detect even small changes in conductivity, making them suitable for analyzing low concentrations of substances. Additionally, conductometric titrations are relatively simple and quick to perform, requiring minimal equipment. They also offer a wide range of applications, as they can be used to determine the concentration of various types of substances, such as acids, bases, and salts.
4. What are some limitations of conductometric titrations?
Ans. Conductometric titrations also have some limitations. One limitation is that they are most effective for substances that undergo a significant change in conductivity during the titration process. For substances with similar conductivities, it may be challenging to accurately determine the endpoint of the titration. Another limitation is that conductometric titrations require a conductometer, which may not be readily available in all laboratories. Additionally, conductometric titrations may be affected by impurities or interfering substances in the solution, leading to inaccurate results.
5. Can conductometric titrations be automated?
Ans. Yes, conductometric titrations can be automated using specialized equipment and software. Automated conductometric titration systems allow for precise and consistent measurements, reducing human error and increasing efficiency. These systems often include titrators with built-in conductometers and sensors, as well as software that controls the titration process and records the data. Automation of conductometric titrations is particularly useful when large numbers of samples need to be analyzed or when high accuracy and reproducibility are required.
