Question
1. Of th following anions,Br ,CO32 ,CI ?, NOg , NO2703 ,s042 and SO , list those ions that meet the following criteria. (1) Gives a precipitate with Ag ion that is insoluble in HNO3. (2) Is involved in an oxidation-reduction reaction as part of a confirmation reaction. (3) Gives a precipitate with Ba2+ ion that is soluble in HNO (4) Evolves a gas when acid is added. (5) Releases an odorous gas as a product. (6) Does not produce a precipitate in any classification or confirmatory reaction described in this experiment.Explanation / Answer
1.) Gives a precipitate with Ag+ ion that is insoluble in HNO3.
Answer: Br-, Cl-, I-
2.) Is involved in an oxidation-reduction reaction as part of a confirmation reaction.
Answer: (CO3)2-
3.) Gives a precipitate with Ba2+ ion that is soluble in HNO3.
Answer: (CO3)2-, (PO4)3-
4.) Evolves a gas when acid is added.
Answer: (CO3)2-, NO3-, NO2-
5.) Releases an odorous gas as a product.
Answer: NO3-, NO2-
6. 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
Answer: SO4^2-
