Chemical Properties

Description
Barium dichloride is a white solid, odorless, hygroscopic chemical substance. Barium dichloride is used in the manufacture of pigments, in the manufacture of other barium salts and in fireworks to give a bright green color. It is one of the most common watersoluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. Barium chloride has wide application in the laboratory.

Hazard Information

General Description
Any of a variety of substances that contain barium. Most are whitish colored crystalline solids. They tend to be soluble in water and denser than water. They may be toxic by inhalation or possibly skin absorption. They are often used to make other chemicals.
Reactivity Profile
BARIUM CHLORIDE may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.
Air & Water Reactions
Water soluble.
Hazard
Ingestion of 0.8 g may be fatal.
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.

Questions And Answer

Soluble barium salt
Barium chloride is one of the most important soluble barium salts, it is also known as "salting barium", the formula is BaCl2, it has colorless monoclinic and colorless cubic two crystals, monoclinic crystal turns into cubic crystal at 962℃. At room temperature it is white lustrous monoclinic crystal, odorless, bitter and salty. It is soluble in water, insoluble in acetone, ethanol and ether, slightly soluble in acid, sulfuric acid. Crystallization from aqueous solution of barium chloride often contains two crystal water. When heated to 113℃, it loses crystal water and becomes anhydrous barium chloride, it is white powder.
Barium chloride
Barium chloride can be used for identification and separation of SO42-ions, purify the brine water, mainly used for the manufacture of barium salts and pigments, it can also be used as hard water softener, wool and leather industry mordant, pesticides for controlling plant pests. Preparation of industrial barium chloride is mainly used barite as material which containing high components of barium sulfate barite, coal and calcium chloride is mixed, and calcined to get barium chloride, reaction is as follows:
BaSO4 + 4C + CaCl2 → BaCl2 + CaS + 4CO ↑.
Chemical properties
It is colorless monoclinic crystal. (Α type) it is soluble in water, slightly soluble in hydrochloric acid, nitric acid, very slightly soluble in alcohol.
Uses
(1) Barium chloride is mainly used for heat treatment of metals, barium salt manufacturing, electronic instruments, and used as water softener.
(2) It can be used as dehydrating agent and analysis reagents, it is used for machining heat treatment Jing, see other barium chloride dihydrate.
(3) Calibration instruments and devices, evaluation methodology, quality assurance/quality control.
Hazardous characteristics
Barium chloride is noncombustible. It is highly toxic. When contacts boron trifluoride, violent reaction can occur. Swallowed or inhaled can cause poisoning, it is mainly through the respiratory tract and digestive tract to invade the human body, it will cause drooling and burning esophagus, stomach pain, cramps, nausea, vomiting, diarrhea, high blood pressure, no law firm pulse, cramps, a lot of cold sweat, weak muscle strength, gait, vision and speech problems, difficulty breathing, dizziness, tinnitus, consciousness usually clear. In severe cases, it can cause sudden death. Barium ions can cause muscle stimulant, then gradually transforms into paralysis. Rat oral LD50150mg/kg, mouse peritoneal LD5054mg/kg, rats are intravenously LD5020mg/kg, orally in dog LD5090mg/kg.
First-aid measure
When skin contacts it, rinsing with water, then thoroughly washing with soap. When eye contacts, flushing with water. So that patients inhaled dust should leave from the contaminated area, move to fresh air place, rest and keep warm, if necessary, artificial respiration should be taken, seek medical attention. When swallowed, immediately rinse the mouth, gastric lavage should be taken with warm water or 5% sodium hydrosulfite for catharsis. Even swallows more than 6h, gastric lavage is also necessary. Intravenous infusion is slowly taken with 1% sodium sulfate of 500ml~1 000ml, intravenous injection can also be taken with 10% sodium thiosulfate of 10ml~20ml. Potassium and symptomatic treatment should be carried out.
Soluble barium salts of barium chloride is rapidly absorbed, so the symptoms develop rapidly, at any time cardiac arrest or respiratory muscle paralysis can cause death. Therefore, first aid must be against the clock.
Solubility in water
Grams which dissolves in per 100 ml of water at different temperatures (℃):
31.2g/0 ℃; 33.5g/10 ℃; 35.8g/20 ℃; 38.1g/30 ℃; 40.8g/40 ℃
46.2g/60 ℃; 52.5g/80 ℃; 55.8g/90 ℃; 59.4g/100 ℃.
Toxicity
See barium chloride dihydrate.
Production method
Barium chloride dihydrate is heated to above 150℃ by dehydration to obtain anhydrous barium chloride products. its
BaCl2 • 2H2O [△] → BaCl2 + 2H2O
Hazards & Safety Information
