Potassium hydrosulfide is an inorganic compound with the formula KSH. This colourless salt consists of the cation K + and the bisulfide anion [SH] −. It is the product of the half-neutralization of hydrogen sulfide with potassium hydroxide. The compound is used in the synthesis of some organosulfur compounds. [1]
Powdered potassium sulfide anhydrous. Potassium sulfide is an inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).

In general the classification of chemical industry products by the Kline matrix is related to the chemicals' worldwide production (measured for example in tons/year) and to their value added. [6] Following this classification, the chemical industry products are divided into four categories: true commodity: high production and high value added
Service industries are those not directly concerned with the production of physical goods (such as agriculture and manufacturing). Some service industries, including transportation , wholesale trade and retail trade are part of the supply chain delivering goods produced in the agricultural and manufacturing sectors to final consumers.
Other terms were developed by the public to explain the technology that they used. Some of these terms were initially widely used, then fell out of the common vernacular. Others failed to "catch on" and never entered common usage in the first place. Sometimes, the technologies themselves were superseded, and the term fell into disuse.
Commodity chemicals are a sub-sector of the chemical industry (other sub sectors are fine chemicals, specialty chemicals, inorganic chemicals, petrochemicals, pharmaceuticals, renewable energy (e.g. biofuels) and materials (e.g. biopolymers)). Commodity chemicals are differentiated primarily by the bulk of their manufacture.
