24 wrz 2024 · Limit test for chloride gives a silver chloride precipitate upon the reaction of chloride ion with silver nitrate in the presence of dilute nitric acid. Here, the standard solution was prepared by taking 1ml of 0.05845% of sodium chloride solution.
Sodium chloride . Principle . It is based upon the chemical reaction between silver nitrate and soluble chlorides in presence of dilute nitric acid to give opalescence of silver chloride. If the Opalescence produced is compared with the standard solution.
The limit test for chlorides is provided to demonstrate that the content of chlorides does not exceed the limit given in the individual monograph in terms of micrograms of chloride ions per gram of the substance being tested.
20 kwi 2019 · Limits test for chloride is a semi-quantitative analytical test to check the chloride impurities in a given pharmaceutical sample. It is performed to identify the traces of chloride impurities which are likely to be present in a substance.
The limit test for chlorides is based on simple reaction between silver nitrate and soluble chlorides to obtain silver chloride which is insoluble in dilute nitric acid, which extracts a common ion effect by furnishing nitrate ions and thereby suppression of dissociation of silver chloride.
26 lip 2021 · Limit tests are quantitative or semi-quantitative tests used to detect and limit small amounts of impurities in substances. They involve comparing the color or turbidity produced by the sample to a standard with a known concentration of impurities. Common limit tests include those for chlorides, sulfates, iron, heavy metals, and arsenic.
9 lut 2021 · The limit test for chloride determines the allowable limit of chloride in a sample. It involves dissolving the sample and standard sodium chloride solution, adding nitric acid and silver nitrate, and observing any opalescence or turbidity after 3 minutes.
