Qualitative Cation Tests Essay

Lab Report availThis document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiments questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students physical composition of lab reports by providing this information in an editable burden which can be sent to an instructor.ObservationsQuestionsA. Write remuneration ionic equations for all reactions that produce a shine.Ag+(aq.) + Cl-(aq.) - AgCl (s)2 Ag+(aq.)+ 2OH- Ag2O (s) + H2O(l)2 Ag+(aq.)+2NH3+ H2O(l) Ag2O (s)+ 2NH4+ (aq.)Pb2+(aq.)+2Cl- (aq.) - PbCl2(s)Pb2+(aq.)+2OH-(aq.) -Pb(OH)2 (s)Pb2+(aq.)+ 2NH3(aq.)+ H2O(l) Pb(OH)2 (s)+ 2NH4+ (aq.)

Identify the cations that precipitate with hydrochloric acid and do not redissolve in the presence of ammonia.Pb2+D. Identify the cations that precipitate upon entree of deuce or threesome drops of atomic number 11 hydroxide but redissolve upon addition of pointless sodium hydroxide.Pb2+,Zn2+E. Identify the cations that precipitate upon addition of two or three drops of sodium hydroxide and be not affected by redundant sodium hydroxide.Ag+,Cu2+,Fe3+F.Identify the cations that precipitate upon addition of two or three drops of aqueous ammonia but redissolve upon addition of senseless aqueous ammonia.Ag+,Cu2+,Zn2+G. Identify the cations that precipi tate upon addition of two or three drops of aqueous ammonia and are not affected additional aqueous ammonia.Pb2+,Fe3+H. What simple test would distinguish Ag+ and Cu2+ ?Upon addition of two or three drops of aqueous ammonia, Ag+ produces brown ppt, which is soluble in the excess reagent, resulting in clear, colorless solution.Upon addition of two or three drops of aqueous ammonia, Cu2+ produces blue ppt, which is soluble in the excess reagent but produces dark blue solution.
