Analytical grade Sodium chloride (NaCl) is one type of salt with a purity of > 99.50 % NaCl content, including other impurities. In laboratories, salt is used as a reagent and a standard solution. This research carried out the salt production process through purification, acidification, neutralization, crystallization, and drying methods. Compared to existing technologies, the advantages of this technology are its simplicity and ability to produce accompanying products. In the first stage of the purification process, the precipitation of sulfate (SO
