iodbenzene

[Eng. iod ( ine ), and benzene.] Chem.: C6H5I. Iodobenzene. An aromatic iodine substitution compound, formed by the action of iodine and benzene, C6H6. It is nece ary to add iodic acid to decompose the hydriodic acid which is formed, or this would act on the C6H5I, re-forming benzene. 5C6H6+4HIO3+41 = 5C6H51+3H2O. Iodbenzene boils at 188°. i-od-Ic, a. [Eng. iod ( ine ); -ic.] Chem.: Of, belonging to, or containing iodine. iodic-acid, 8. Chem.: HIO3. A monobasic acid obtained by boiling iodine with strong nitric acid, or by pa ing chlorine into twenty parts of water containing one part of finely-divided iodine in suspension 12+5Cl2+6H2O=10HCl+2HIO3. By evaporation the iodic acid is obtained in transparent six-sided tables, which, when heated to 170°, is converted into the anhydride 1205. Iodic acid is very soluble in water. The solution reddens litmus, and then bleaches it. Iodic-acid is reduced by sulphurous acid. An aqueous solution of iodic acid is a powerful oxidizing agent. iodic-quicksilver, s. Min.: The same as COCCINITE (q. v.). iodic-silver, s . Min.: Iodargyrite (q. v.). [IODYRITE.] I-o-dide, s . [Eng. iod (ine); -ide .] Chem.: A compound formed by the union of iodine with an element or with a radical.
