Other Experimental

Slowly attacked by boiling concn acids, not affected by hot soln of alkali hydroxides; slowly darkened by light.;It dissolves in the presence of excess iodide ion forming an AgI-2 complex; silver iodide exists in one of three crystal structures depending on the temp, a phenomenon frequently referred to as trimorphism. Below 137 °C, silver iodide is in the cold cubic, or gamma form; at 137-145.8 °C, it exists in the green-yellow colored hexagonal, or beta form; above 145.8 °C, the yellow cubic or alpha form of silver iodide is the stable crystal structure.;Silver iodide has the broadest wavelength sensitivity in the visible spectrum.
