Qualitative analysis studies require the use of a large number of chemical reagent, each of which must be treated with care. To illustrate this statment, list the reagents used to determine and confirm the presence of Ag+ ion in a sample, and describe the safety problems associated with each. please explain!!!

Expert Solution

Qualitative analysis of Ag+ ions

Ag+ belongs to the first group that is Group - I metal ions

The first test is addition of dilute aqueous HCl, which forms AgCl as white precipitate.

HCl : is highly corrosive and toxic chemical. Proper safety measures such as clothing must be worn and spills must be avoided. Work must be acrried out in proper well ventillated fume hood. Causes respiratory infectiona and skin burn.

The confirmatory test for Ag+ is, addition of aqueous NH3 to the precipitate of AgCl. the precipitate dissolves due to the formation of soluble complex Ag(NH3)2Cl.

NH3 is again a highly corrsove and irritant chemical. Vapors If accidentally inhaled, doctors immediate attention is advised. If spilled wash with lots of water. Wear proper clothing while working.
