Bismuth iodate

Chemical compound From Wikipedia, the free encyclopedia

Bismuth iodate is an inorganic compound with the chemical formula Bi(IO3)3. Its anhydrate can be obtained by reacting bismuth nitrate and iodic acid, dissolving the resulting precipitate in 7.8 mol/L nitric acid, and heating to volatilize and crystallize at 70 °C;[2] The dihydrate can be obtained by reacting bismuth nitrate and potassium iodate or sodium iodate. It is obtained by evaporation and crystallization in 7 mol/L nitric acid at 50 °C.[1] Its basic salt BiOIO3 is known.[3]
