Аммоний-никель сернокислый химические свойства, назначение, производство
Химические свойства
Nickel ammonium sulfate is a green, odorless
powder.
Использование
Nickel electrolyte for electroplating.
Определение
ChEBI: A nickel coordination entity comprising ammonium, nickel and sulfate in which the ratio of ammonium to iron(2+) to sulfate ions is 2:1:2.
Общее описание
NICKEL AMMONIUM SULFATE is a green crystalline solid. Mildly toxic, carcinogenic. When heated to decomposition NICKEL AMMONIUM SULFATE emits highly toxic fumes of metallic nickel, oxides of sulfur, and oxides of nitrogen (Lewis, 3rd ed., 1993, p. 910). The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. NICKEL AMMONIUM SULFATE is used for electroplating nickel.
Реакции воздуха и воды
Water soluble. Forms an acidic aqueous solution.
Профиль реактивности
NICKEL AMMONIUM SULFATE is a "double salt" that is a weak oxidizing agent. Gives an acidic solution when dissolved in water.
Опасность
See nickel
Угроза здоровью
Inhalation causes irritation of nose and throat. Ingestion causes vomiting. Contact with eyes causes irritation. Contact with skin may cause dermatitis.
Пожароопасность
Special Hazards of Combustion Products: Toxic oxides of nitrogen may be formed in fire.
Профиль безопасности
Confirmed human
carcinogen. Poison by ingestion. When
heated to decomposition it emits toxic
fumes of NOx, SOx, and Ni.
