1130 K Boiling point. It aims to help students hone their analytical and problem-solving skills by presenting detailed approaches to solving chemical problems.
It is also hygroscopic converting first to the dihydrate BaCl 2 H 2 O 2.
Barium chloride dihydrate molar mass. Barium chloride is an inorganic compound with the formula Ba Cl 2. 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 BaCl 2 H 2 O 2. It has limited use in the laboratory and. Barium stimulates striated cardiac and smooth muscle regardless of innervation.
It is antagonistic to all muscle depressants no matter whether they act primarily on nerve or muscle. Initial stimulation of contraction leads to vasoconstriction through direct action on arterial muscle peristalsis through action on smooth muscle tremors and cramps through action on the skeletal muscles and. Predict Barium Chloride Dihydrate Purified is an inorganic compound and one of the most common water soluble salts of barium.
Barium is mono-atomic and its ionic state is Ba2 B a X 2. An Email Id is required to process your orders. Like most other barium Barium Chloride CAS 10361-37-2 - GHS Pipe Marking Label Keep your hazardous materials labeled and facility safe with this durable.
