This standard specifies a general method for the determination of mg content in inorganic chemical products using the complexed Titrimetric method. This method utilizes disodium ethylenediaminetetraacetate (EDTA) as a complexing agent to form a stable complex with mg ions at a pH of 10. It is suitable for samples with mg ion content ranging from 1 mg to 200 mg. The standard emphasizes the use of analytically pure reagents and tertiary water, and refers to the titration solutions and reagents required for the preparation of relevant standards. Safety should be paid attention to during the operation, and protective measures must be in place to prevent the toxic or corrosion effects of the reagents.
