Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical compound with the chemical formula NaHSO3. Sodium bisulfite is a food additive with E number E222. This salt of bisulfite can be prepared by bubbling sulfur dioxide in a solution of sodium carbonate in water. Sodium bisulfite in contact with chlorine bleach (aqueous solution of sodium hypochlorite) will generate heat and form sodium bisulfate and sodium chloride. Uses in food

Antiscalant Chemical is a liquid antiscalant for RO membrane system. Antiscalant Chemical controls inorganic scales of calcium, magnesium, barium, stronium, fluoride, iron and silica. Antiscalant is a pretreatment water additive for reverse osmosis system that is highly effective in preventing the membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent the through the system.

East india chemical Iron(III) chloride, also called ferric chloride, is an industrial scale commodity chemical compound, with the formula FeCl3 and with iron in the +3 oxidation state. The colour of iron(III) chloride crystals depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple-red. Anhydrous iron(III) chloride is deliquescent, forming hydrated hydrogen chloride mists in moist air. It is rarely observed in its natural form…

Hydrazine is an inorganic compound with the chemical formula N2H4 (also written H2NNH2), called diamidogen, archaically. A simple pnictogen hydride, it is a colorless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic and dangerously unstable unless handled in solution as e.g., hydrazine hydrate (NH2NH2 · xH2O ). As of 2015, the world hydrazine hydrate market amounted to $350 million.

East india chemical is Hypochlorous acid (HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions. HClO cannot be isolated from these solutions due to rapid equilibration with its precursor. Sodium hypochlorite (NaClO) and calcium hypochlorite (Ca(ClO)2), are bleaches, deodorants, and disinfectants.

Ultrasonic and megasonic cleaners are used in varied applications to clean substrate surfaces. In a typical assembly, a cleaning system includes a tank that holds a fluid medium such as an aqueous solution, which generally includes additives such as surfactants and detergents that enhance the cleaning performance of the system. Lately, more distinctive means of delivery have been utilized, particularly for single wafer applications. In one example, megasonics is diverted into a stream of fluid…

East india chemicals Calcium acetate is a chemical compound which is a calcium salt of acetic acid. It has the formula Ca(C2H3O2)2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH3COO)2•H2O) is the common form. Other names Acetate of lime Calcium ethanoate Calcium diacetate
