. Unlike most metal iodates, it is practically insoluble in water.

Production

Silver iodate can be obtained by reacting

silver nitrate Silver nitrate is an inorganic compound with chemical formula . It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called ''lunar causti ...
