copper in solution sodium hydrosulphide


Posted on November 13, 2018



Sodium hydrosulfide - WikipediaNaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution. Solid NaHS is colorless, and typically smells like H2S owing to hydrolysis by atmospheric moisture. In contrast with sodium sulfide (Na2S), which is insoluble in organic.copper in solution sodium hydrosulphide,Sodium Hydrosulfide (NaSH) - AkzoNobelAkzoNobel is the global producer of sodium hydrosulfide (NaSH), which is available in different aqueous solutions (including 30%, 40%, 42%, 45% and 60%).
