Sodium Hydrosulphite - Overview

Sodium Hydrosulfide is an inorganic compound with the formula NaHS. It is colorless needle-like crystal and easily deliquesced. It is soluble in water and alcohols. Crystalline NaHS exists in two phase transitions. At temperatures above 360 K, NaHS assumes the NaCl structure, which implies that the HS− behaves as a spherical anion due to its rapid rotation leading to equal occupancy of eight equivalent positions. Below 360 K, a rhombohedral structure forms, and the HS− sweeps out a discoidal shape. Below 114 K, the structure becomes monoclinic.

Product Applications

In Paper Industry, it is used as a make-up chemical in the manufacture of paper by Kraft process and to prepare synthetic cooking liquor. It may also be used as a scrubbing media for residual chlorine dioxide produced and used up in mill bleach plants. In Leather industry, it is used to remove hair from hides before processing for leather and in preparation of sodium polysulfide immersion which helps to accelerate the dry skin soft.
