Question

Discuss the effect of temperature humidity on the hydrated forms of barium chloride?
please ask me​

Answer 1

Answer:

Barium chloride is an inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like most other barium salts, it is white, toxic, and imparts a yellow-green coloration to a flame. It is also hygroscopic, converting first to the dihydrate BaCl2(H2O)2. It has limited use in the laboratory and industry.

Answer 2

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 $113^{0} C$, it  loses crystal water and becomes anhydrous barium chloride, it is in white powder.

Explanation:

• Barium chloride is one of the most important soluble barium salts, it is known as "salting barium", the formula is $BaCl_{2}$, it has colorless monoclinic and colorless cubic two crystals, monoclinic crystals turns into cubic crystals at $962^{0} C$.
• At room temperature it is white lustrous monoclinic crystals, odorless, bitter and salty.
• Barium chloride can be prepared from barium hydroxide or barium carbonate.
• These basic salts react with hydrochloric acid to give hydrated barium chloride.
• when heated, it  at decomposes at $480^{0}C$ to the oxide and $SO_{2}$ gas.
