Lead Periodates

In common with many other metals lead forms several periodates, most of which may be regarded as basic salts, or salts of polybasic periodic acids.

By precipitating lead nitrate solution with sodium iodate, Rammelsberg obtained a white, microcrystalline salt, to which he attributed the formula Pb(IO4)2.2PbO.2H2O or Pb3I2O10.2H2O. When strongly heated this salt loses water, iodine, and oxygen, leaving PbI2.5PbO. According to Kimmins, however, it gradually loses its water at 275° C., leaving the dark yellow anhydro-salt Pb(IO4)2.2PbO; and it is converted into the red normal salt Pb(IO4)2 by prolonged heating with concentrated nitric acid.

Giolitti has obtained rather different results. According to this observer, the salt obtained by adding a dilute acetic acid solution of lead acetate to a cold solution of the salt K2HIO5, to which the formula Pb3I2O10.2H2O was attributed by Rammelsberg, is PbHIO5; and this when heated to 130°-140° C. yields the anhydro-salt Pb2I2O9 as a red powder. The hydrated salt PbHIO5.H2O is formed when a solution of periodic acid is added to a dilute acetic acid solution of lead acetate; and Pb2HIO6 results from the prolonged heating of PbHIO5 with water. Lastly, the salt Pb3I2O10.H2O, containing one molecule of water less than Rammelsberg's salt, is probably formed when PbHIO5 is heated in dilute nitric acid with lead hydroxide.
