During your Qualitative Analysis the ions in this group will not precipitate as chlorides sulfides or hydroxides.The test for ammonium ions must be done first becauseTo detect K+(aq) in a solution that is known to contain only K+(aq) and Na+(aq)To detect Ca2+(aq) in a solution that is known to contain only Ca2+(aq) Fe3+(aq) and Al3+(aq) you mustTo detect Mg2+(aq) in a solution that is known to contain only Mg2+(aq) Cu2+(aq) and Na+(aq)These ions form few insoluble compoundsAccording to your flow chart how will you reduce Mg3+(aq) to Mg 2+(aq)? According to your flow chart how will you oxidize K+(aq)? During the analysis of your Qual IV unknown how will you precipitate CaC2O4(s) from a solution containing Mg2+(aq) and Ca2+(aq) ions ?
