Barium hydroxide is an inorganic compound with the chemical formula Ba (OH)two, white crystalline powder, soluble in water[2]Ethanol, easily soluble in dilute acid, is mainly used for making special soaps, pesticides, and also for softening hard water, refining beet sugar, boiler descaling, glass lubrication, etc.
Chinese name
Barium hydroxide[3]
Foreign name
Barium hydroxide[3]
chemical formula
Ba(OH)two
molecular weight
one hundred and seventy-one point three four two[3]
Solubility: soluble in hot water, slightly soluble in ethanol, soluble in dilute acid[1][4]
chemical property
1、Ba(OH)twoIt has strong alkalinity, which is the strongest among alkaline earth metal hydroxides. It can make phenolphthalein solution red and purple litmus blue.
2、Ba(OH)twoIt can absorb carbon dioxide from the air and transform it intobarium carbonate：Ba(OH)two+ COtwo= BaCOthree↓ + HtwoO
3、Ba(OH)twoIt can neutralize with acid, and generate precipitation when encountering sulfuric acid: Ba (OH)two+ HtwoSOfour= BaSOfour↓+2HtwoO

Body protection: wear rubber acid and alkali resistant clothes.
Hand protection: wear rubber acid and alkali resistant gloves.
Others: Smoking, eating and drinking are prohibited at the work site.After work, take a shower and change clothes.Store the clothes contaminated by poisons separately and use them after washing.Keep good hygiene habits.
First aid measures
Skin contact: Take off the contaminated clothes and wash the skin thoroughly with soapy water and clean water.
Eye contact: Lift the eyelid and flush with flowing water or physiological saline.Get medical attention.
Inhalation: quickly leave the site to a place with fresh air.Keep the respiratory tract unobstructed.If breathing is difficult, give oxygen.If breathing stops, perform artificial respiration immediately.Get medical attention.
