Iodometry is a quantitative analytical technique used to determine the concentration of certain substances, particularly oxidizing agents, in a solution. It involves the use of iodine and sodium thiosulfate as reagents. In this method, iodine is added to the solution, where it reacts with the analyte, and the remaining unreacted iodine is then titrated with sodium thiosulfate until a color change indicates the endpoint. This technique is commonly applied in various fields, including chemistry, environmental science, and food analysis. Iodometry is valued for its accuracy and simplicity, making it a popular choice for laboratories needing to measure specific concentrations of oxidizing agents effectively.
