WitrynaSodium hydrosulfide is a yellow chemical compound with the formula NaHS. It has a low melting point of 350 °C. It’s obtained by half-neutralization of hydrogen sulfide (H2S) with sodium hydroxide. Generally NaHS undergoes two phase transitions. Below 360 K, a rhombohedral structure forms, and Below 114 K, the structure becomes monoclinic.
