Suppose you are given an aqueous solution containing Cl(aq), OH (aq) and " 5042 (aq). Suppose you add the following ions, in excess each time, one at a time. Suppose your aim is to completely precipitate one chemical species at a time, leaving other/s in solution. The final addition will have to leave no ion left in solution. Which answer has the correct order of ions, when added in that order, will fulfill this requirement? [Assume each ion completely precipitates whatever it precipitates). o Excess Ba2+(aq) --followed by--> Excess Sr2+(aq) --followed by--> Excess Ag+ (aq) O Excess Ca2+(aq) --followed by--> Excess Ba2+(aq) --followed by--> Excess Na*(aq) O Excess Ba2+ *(aq) --followed by --> Excess Ag2+ *(aq) --followed by--> Excess Na*(aq) O Excess Ca2+(aq) --followed by --> Excess K+(aq) --followed by--> Excess Na+(aq) O Excess Hg2+ (aq) --followed by--> Excess Ba2+ (aq) --followed by--> Excess Ag+ (aq)
