Phosphorous acid can be used in many places. People can use it in industry, and we also can use it in agriculture! You can't imagine how useful it was! I am the freelance writer for e-commerce website in the chemistry. Guidechem.comis just a place for you to look for some chemicals. Our guidechem provide the most convenient conditions for the international buyers and let these leads benefit all the business people. Guidechem chemical B2B network provides information on china and global chemical market quotation and relative chemical Information. Guidechem Chemical Network providing the most complete information of the chemical industry.So I write this article talk about Phosphorous acid. First of all, I will tell you some basic information bout phosphorous acid. We also called it Orthophosphorous Acid, one of several oxygen acids of phosphorus, used as reducing agent in chemical analysis. It is a colourless or yellowish crystalline substance with a garliclike taste. An unstable compound that readily absorbs moisture, it is converted to phosphoric acid in the presence of oxygen or when heated above 180° C. Phosphorous acid forms salts called phosphites, also used as reducing agents. It is prepared by dissolving tetraphosphorus hexoxide or phosphorus trichloride in water. The most important use of phosphorous acid is the production of phosphonates which are used in water treatment. Phosphorous acid is also used for preparing phosphite salts, such as potassium phosphite. These salts, as well as aqueous solutions of pure phosphorous acid, have shown effectiveness in controlling a variety of microbial plant diseases, in particular, treatment using either trunk injection or foliar containing phosphorous acid salts is indicated in response to infections by phytophthora and pythium-type plant pathogens (both within class oomycetes, known as water molds), such as dieback/root rot and downy mildew. Anti-microbial products containing salts of phosphorous acid are marketed in Australia as 'Yates Anti-Rot'; and in the United States of America, for example, aluminum salts of the monoethyl ester of phosphorous acid (known generically as 'Fosetyl-Al') are sold under the trade name 'Aliette'. Phosphorous acid and its salts, unlike phosphoric acid, are somewhat toxic and should be handled carefully. By: yang W
