Qualitative Cation Tests Essay

science laboratory cover up AssistantThis document is non meant to be a substitute for a statuesque laboratory report. The Lab Report Assistant is simply a thickset 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 paternity of lab reports by providing this information in an editable file which can be displace to an instructor.ObservationsQuestionsA. Write net ionic equations for every last(predicate) reactions that produce a sicken.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 sum total of cardinal or iii drops of atomic number 11 hydroxide barely redissolve upon access of glut sodium hydroxide.Pb2+,Zn2+E. Identify the cations that precipitate upon addition of twain or ternion drops of sodium hydroxide and are not bear on by additional sodium hydroxide.Ag+,Cu2+,Fe3+F.Identify the cations that precipitate upon addition of two or three drops of sedimentary ammonia but redissolve upon addition of excess sedimentary ammonia.Ag+,Cu2+,Zn2+G. Identify the cations that precipitate upon addition of two or three drops of aqueous ammonia and are not affected additional aqueous ammonia.Pb2+,Fe3+H. What simple shew 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 stern ppt, which is soluble in the excess reagent but produces dark blue solution.
