Question
A mixture of solid chloride salts known to contain only some of the cations of Experiment 12 is partially dissolved in cold water to give a white precipitate and a colorless solution. The solution is decanted from the precipitate. Addition of 5 M NH4Cl(aq) solution and enough 6 M NH3(aq) to make the solution basic to litmus resulted in no change in the solution. The addition of (NH4)2C2O4(aq) resulted in the formation of a white a precipitate. Using this data, indicate whether the listed cations are most likely present, most likely absent or unable to be determined. Ag+, Fe3+, Al3+, Ca2+, Cr3+
