Iodic acid is an organic compound with the formula HIO3, and its systematic name is the same with the product name. With the CAS registry number 7782-68-5, it is also named as Hydrogeniodate. It belongs to the product categories of Inorganics; Acids & Bases; ACS GradeChemical Synthesis; Essential Chemicals; Inorganic Acids; Synthetic Reagents. Its EINECS number is 231-962-1. In addition, the molecular weight is 175.91. This chemical should be sealed and stored in a cool and dry place. It is used as a strong acid in analytical chemistry. It may be used to standardize solutions of both weak and strong bases, with methyl red or methyl orange as the indicator. In salt industry, it also can be used to synthesize sodium iodate or potassium iodate for increasing iodine content of salt. This chemical can be produced by oxidizing I2 with chlorine in an aqueous solution.
Physical properties of Iodic acid are: (1)ACD/LogP: -3.177; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -6.60; (4)ACD/LogD (pH 7.4): -6.68; (5)ACD/BCF (pH 5.5): 1.00; (6)ACD/BCF (pH 7.4): 1.00; (7)#H bond acceptors: 3; (8)#H bond donors: 1; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 54.37 Å2.
