Ihe Nyocha COD n'ịntanetị
Ụkpụrụ Nchọpụta
Tinye ihe ngwọta potassium dichromate a maara nke ọma na ihe nlele mmiri, ma jiri nnu ọlaọcha dị ka ihe na-akpali akpali na mercury sulfate dị ka ihe na-ekpuchi ihe mkpuchi na ihe siri ike nke acid. Mgbe mmeghachi omume mgbaze dị elu na nrụgide dị elu gasịrị, chọpụta nnabata nke ngwaahịa ahụ na ogologo ebili mmiri kpọmkwem. Dịka iwu Lambert Beer si dị, enwere njikọ kwụ ọtọ n'etiti ọdịnaya nke mkpa oxygen kemịkalụ dị na mmiri na nnabata, wee chọpụta mkpokọta nke mkpa oxygen kemịkalụ dị na mmiri. Rịba ama: Ọ na-esiri ike ịgbaze ihe dị ka hydrocarbons aromatic na pyridine na ihe nlele mmiri, enwere ike ịgbatị oge mgbaze nke ọma.
