Potassium bisulfate Chemical Properties,Uses,Production

Chemical Properties

Also known as acid potassium sulfate and potassium acid sulfate, KHS04 is water soluble, white deliquescent crystals,which melt at 214°C. It is used in wine making, fertilizer manufacture, and as a flux and food preservative.

Uses

As flux in analysis of ores and siliceous Compounds.

General Description

Potassium bisulfate is a colorless crystalline solid with a sulfur odor. Potassium bisulfate may cause illness from ingestion. If heated to high temperatures Potassium bisulfate may emit toxic fumes. Potassium bisulfate is used to make fertilizers and wine.

Air & Water Reactions

Fused salt is deliquescent, Soluble in water, yielding a corrosive acidic solution.

Reactivity Profile

Acidic salts, such as Potassium bisulfate , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Purification Methods

Crystallise it from H2O (1mL/g) between 100o and 0o. It is also formed when a warm solution of K2SO4 in conc H2SO4 is cooled down.
