| Iodic anhydride reacts with rubidium carbonate to form the Rubidium iodate, RbIO3, and the salt is also produced by passing chlorine into a hot concentrated solution of rubidium iodide and hydroxide. It forms monoclinic crystals isomorphous with those of potassium iodate, and of density 4.559 at 14° C. At 23° C. the solubility is 2.1 grams in 100 grams of water. It yields acid iodates, such as RbIO3,HIO3 and RbIO3,2HIO3, and also compounds of the type RbIO3,F2 and RbIO3,HIO3,4HF. |
