Coulometry is a technique used in analytical chemistry to determine the amount of a substance present in a sample based on the amount of electricity required to undergo a chemical reaction.
Principle of Coulometry
In coulometry, the substance of interest undergoes a chemical reaction at an electrode when a known electric current is passed through the solution. The amount of substance present can be calculated by measuring the total charge passed during the reaction.
Types of Coulometry
There are two main types of coulometry: constant-current coulometry and controlled-potential coulometry. In constant-current coulometry, a steady electric current is passed through the solution, while in controlled-potential coulometry, the potential is kept constant throughout the reaction.
Applications of Coulometry
Coulometry is used in various fields such as environmental analysis, pharmaceuticals, and electroplating. It is particularly useful in determining trace amounts of substances in samples and in studying reaction mechanisms.
Accuracy and precision are key advantages of coulometry, making it a valuable tool in quantitative analysis. Additionally, coulometry is a versatile technique that can be tailored to suit different analytical needs.
Overall, coulometry is a powerful analytical technique that plays a crucial role in various industries where precise measurements of substances are required.
