Apply all of the results and observations made in this experiment to the examples below. For each report what each cited test reveals about the unknown; the identity of the unknown ion and suggest another test which would confirm that identity.

a. Addition of Cl2 and Ch2Cl2 to an aqueous solution of an unknown halide led to a dark Ch2Cl2 layer. Addition of 0.1M AgNO3 to another sample of the same unknown halide ion solution generated a light yellow ppt; addition of concentrated NH3 to the same solution left a cloudy solution.

b. Addition of acidic 0.1M NaNO2, 0.5M HNO3 and CH2Cl2 to an aqueous solution of an unknown halide ion resulted in a colorless CH2Cl2 layer.
