Abstract : A limit test is a quantitative or semi-quantitative test that is developed to identify and regulate a small amount of impurities that are likely to be present in the substance. In this experiment, AgNO3 is reacted with soluble chloride to produce precipitates of AgCl, which is insoluble in diluted HNO3. The amount of silver chloride that is generated, or the total number of chloride ions that are present in the substance, is directly proportional to the degree to which precipitation occurs. Under the same experimental conditions, the opalescence that is produced in the test solution is compared to the opalescence that is produced in a reference or standard solution.
