Sulfur color reagent AB solution

There are two preparation methods, one is the direct method, which involves accurately weighing a certain amount of reference substance, dissolving it in an appropriate solvent, and then adding it to a volumetric flask. If the reagent meets the requirements of the reference substance (composition and chemical formula match, high purity, stability), a standard solution can be directly prepared by accurately weighing an appropriate amount of the reference substance, dissolving it, and preparing it in a volumetric flask of a certain volume. The weight W of the reference substance to be weighed can be calculated by the following formula: W=Μ V · molar mass of the reference substance. In the formula, Μ and V represent the molar concentration and volume of the solution to be prepared, respectively. The concentration of the standard solution can be calculated using the above formula.; Another method is calibration,
