Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide (H2S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an … Zobacz więcej Crystalline NaHS undergoes two phase transitions. At temperatures above 360 K, NaSH adopts the NaCl structure, which implies that the HS behaves as a spherical anion owing to its rapid rotation, leading to equal … Zobacz więcej One laboratory synthesis entails treatment of sodium ethoxide (NaOEt) with hydrogen sulfide: NaOCH2CH3 … Zobacz więcej Thousands of tons of NaSH are produced annually. Its main uses are in cloth and paper manufacture as a makeup chemical for sulfur used in the kraft process, as a flotation agent in copper mining where it is used to activate oxide mineral species, and in the leather … Zobacz więcej Witryna29 mar 2024 · Extracted and analyzed data from source records in medical records (e.g., adverse drug reaction, laboratory and diagnostic test results, drug infusion) from Melanoma Clinical Trials
