Question

Answer the following questions based on the following anions: Br^-, CO3^2-, Cl^-, I^-, NO3^-, NO2^-, PO4^3-, SO4^2-, SO3^2-.

1.) Which anions give a precipitate with Ag^+ ion that is insoluble in HNO3?

2.) Which anions are involved in an oxidation-reduction reaction as part of a confirmation reaction (see list of confirmation reactions below).

3.) Which anions give a precipitate with Ba^2+ ion that is soluble in HNO3.

4.) Which anions evolve a gas when acid is added.

5.) Which anions release an odorous gas as a product.

6.) Which anions do not produce a precipitate in any of the following classification or confirmatory reactions.

Classification Reaction 1: Formation of insoluble salts, such as BaCO3, BaSO4, BaSO3, Ba3(PO4)2

Classification Reaction 2: Formation of volatile products when H3O^+ ion is added to such anions as CO3^2-, NO2^-, SO3^2- ions

Classification Reaction 3: Formation of insolube silver salts, such as AgBr, AgCl, AgI

Sulfate Ion Confirmatory Reaction: Na2SO4 dissolved in water, then add BaCl2 solution, then add HNO3

Sulfite Ion Confirmatory Reaction: Na2SO3 dissolved in water, then add H2SO4

Nitrate Ion Confirmatory Reaction: NaNO3 dissolved in FeSO4, then add H2SO4

Nitrite Ion Confirmatory Reaction: NaNO2 dissolved in water, then add H2SO4

Carbonate Ion Confirmatory Reaction: Na2CO3 placed in water, then add H2SO4.water

Phosphate Ion Confirmatory Reaction: Na3PO4 dissolved nitric acid, then add (NH4)2MoO4

Halide Ion Confirmatory Reaction: NaCl dissolved in water, then add chlorine water, then add CH2Cl2

1. Nitric acid (even concentrated) is essentially an aqeuous solution. Hence, the solubility rules are applicable. Thus,

Br-, Cl-, I-, SO42-will form precipitate with Ag+ ion that is insoluble in HNO3.
