Barium Chromate
Barium chromate, yellow orthorhombic powder crystal. It is used to make pigments, ceramics, glass, safety matches, etc., and to test the existence of chromic acid.
Barium Hydroxide Monohydrate
Barium hydroxide is the chemical compound with the formula Ba(OH)2. Also known as baryta, or baryta-water, it is one of the principal compounds ofbarium. The white granular monohydrate is the usual commercial form. Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Its clear aqueous solution is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water. This allows the use of indicators such as phenolphthalein or thymolphthalein (with alkaline colour changes) without the risk of titration errors due to the presence ofcarbonate ions, which are much less basic.
Barium Hydroxide Octahydrate
Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Its clear aqueous solution is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, asbarium carbonate is insoluble in water. This allows the use of indicators such as phenolphthalein or thymolphthalein(with alkaline colour changes) without the risk of titration errors due to the presence of carbonate ions, which are much less basic. Barium hydroxide is used in organic synthesis as a strong base, for example for the hydrolysis of esters and nitriles.

They can change the permeability of bacterial plasma membrane, make the cytoplasmic substances of bacteria permeate, and hinder their metabolism It has strong killing effect on Gram-positive bacteria, but has no effect on Pseudomonas aeruginosa, acid fast bacteria, virus and bacterial spore. It can combine with protein rapidly, and reduce the effect significantly in the presence of blood, cotton, cellulose and organic matter.
