Silver iodide is an inorganic compoundwiththeformula AgI. The compound is a bright yellow solid,butsamplesalmost always contain impurities of metallicsilverthatgive a gray coloration. The silvercontaminationarisesbecause AgI is highly photosensitive. Thisproperty isexploited insilver-basedphotography..
Also, what is AgI in chemistry?
Silver iodide is an inorganic compound whichishighlyphotosensitive (reacts when exposed to light). It isalsocalledsilver (I) iodide or iodargyrite. Formula andstructure:Thechemical formula of silver iodide is AgIanditsmolar mass is 234.77 g/mol.
Subsequently, question is, what does silver iodide do to the human body? Exposure to high levels of silver overalongperiod of time can result a gray orblue-graydiscolorationof the skin and other tissues known asargyria.While thiscondition is permanent, it is thought to only beacosmetic problemthat is not otherwise harmful to health(ATSDR,1990; ATSDR,1999).
Also question is, what color is AgI?
