What elements are in AgI?

19
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.


Keeping this in view, 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.

Also Know, 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).

Besides, what color is AgI?

Does AgI precipitate?

A yellowish solid quickly precipitates.Thesolidis a mixture of the two principal phases.Dissolutionof theAgI in hydroiodic acid, followed bydilution withwaterprecipitates β-AgI.Alternatively,dissolutionof AgI in a solution ofconcentrated silvernitrate followedby dilutionaffordsα-AgI.

Why is my AgI yellow?

AgCl is white while AgI is yellow incolour.Assize of anion increases the polarisation increases andhencecolourintensity of the compound increases. Hence AgCl formswhitecolourand AgI yellow colour.
