Standard Addition Method

The Standard Addition Method is a technique used in analytical chemistry to improve the accuracy of measurements. When measuring the concentration of a substance in a sample, you can add a known amount of that substance to the sample. By comparing the changes in the sample's response (like a color change or intensity) before and after the addition, you can better determine the original concentration of the substance. This method helps account for any potential interference from other components in the sample, leading to more reliable and precise results.
