WebPurification Methods: Dissolve iodic acid in the minimum volume of hot dilute HNO3, filter and evaporate in a vacuum desiccator until crystals are formed. Collect the crystals and wash them with a little cold H2O and dry them in air in the dark. It is soluble in H2O: 269g/100mL at 20o and 295g/100mL at 40o. Websecond is that the iodide ion is oxidized by air. The way to prevent the volatilization of I2 is to add an excess of KI (generally 2-3 times larger than the theoretical value), I ̄, IO3 ̄ converts to I3 ̄ (red-brown), a milder oxidizing agent IO3 ̄ (aq) + 8 I ̄ (aq) + 6 H+(aq) → 3I3 ̄ (aq) + 3H2O (l) a part of the I3 ̄ then oxidizes the ascorbic acid in the sample.
