Wet Chemical Analysis

Another common method used in elemental analysis is the determination of silver by precipitating with hydrochloric acid to form silver chloride. Titrimetric procedures have long been used to determine the concentration of a specific element. Knowing the concentration and volume of the titrant used in the analysis, one can calculate what the concentration of the specific element of interest once the endpoint is reached. Colorimetric analysis involves the addition of an indicator which changes color when added to a solution. The intensity of the color is directly proportional to the concentration of the substance in solution. That is, the darker the color the more of that species is present in the solution.
