When treated wi th a solution of ammonium sulfate, an un known solution gave no precipitate. A white precipitate formed when ammonium oxalate, (NH4)2C204. was added. After the precipitate was removed by centrifugati on, the clear solution was treated with Na HPO4 and NaOH and no precipitate was formed. When a separate sample of the un known solution was treated with sodium hydroxide, ammonia gas was produced which turmed red litmus to blue. This unknown solution contained O only Ca2 and NH4 +1 O Ba*2, Mg*2 and NH,*1 O Ca+2, Mg*2 and NH,*1 only Ba+2 and Mg*2 none of the above is correct

The unknown solution contained… (multiple choice)
When treated with a solution of ammonium sulfate, an un known solution gave no precipitate. A white precipitate formed when ammonium o xalate, (NH4)2C20,, was added. After the precipitate was removed by centrifugati on, the clear solution was tre ated with Na HPO4 and NaOH and no precipitate was formed. When a separate sample of the unknown solution was treated with sodium hydroxide, ammonia gas was produced which turnmed red litmus to blue. This unknown solution contained O only Ca2 and NH,1 Ba*2, Mg*2 and NH+1 O Ca+2, Mg*2 and NH,+1 O only Ba*2 and Mg*2 none of the above is correct
