Sodium ethyl xanthate °C. It is the conjugate base of the unknown strong acid with p"K" of 1.6 and p"K" estimated as 12.4 for the conjugate base. Sodium ethyl xanthate easily adsorbs on the surface of solid sulfides. Xanthate are susceptible to hydrolysis and oxidation: These reactions require acidic conditions. Sodium ethyl xanthate can be identified through optical absorption peaks in the infrared (1179, 1160, 1115, 1085 cm) and ultraviolet (300 nm) ranges. There are at least six chemical detection methods: Sodium ethyl xanthate can also be quantified using gravimetry, by weighing the lead xanthate residue obtained after reacting SEX with 10% solution
Ethyl methanesulfonate (a transition mutation). This changes the genetic information, is often harmful to cells, and can result in disease. EMS is often used in genetics as a mutagen. Mutations induced by EMS can then be studied in genetic screens or other assays. Ethyl methanesulfonate Ethyl methanesulfonate (EMS) is a mutagenic, teratogenic, and possibly carcinogenic organic compound with formula CHSO. It produces random mutations in genetic material by nucleotide substitution; particularly by guanine alkylation. This typically produces only point mutations. It can induce mutations at a rate of 5x10 to 5x10 per gene without substantial killing. The ethyl group of EMS reacts
