Lead(II) iodate is an inorganic compound with the molecular formula Pb(IO3)2.

Lead iodate can be precipitated precisely by simultaneous dropwise addition of equivalent solutions of lead nitrate and potassium iodate with water as a solvent at around 60 °C.

Many other group 1 elements can be used in place of potassium to add iodate to the reaction due to solubility of group 1 element iodates.

Lead(II) iodate can then be titrated in the presence of hydrochloric acid and chloroform to indicate the exact amount of lead that was dissolved from the original ore sample.

In this chemical process lead(II) iodate is used to isolate the lead found in a sample of ore from other chemicals present so that it can be studied and quantitated effectively.
