Identifying Non-Metal Ions

C8__Chemical-Analysis

Carbonate Ions

1. Add dilute acid to sample.
2. Acid reacts to make gas.
3. Bubble the gas through limewater.
4. If is present there is a carbonate ion.

Halide Ions

1. Add dilute (nitric acid) to sample.
2. Add dilute silver nitrate solution.
3. Halide ions will produce a precipitate.
   1. Chloride white
   2. Bromide cream
   3. Iodide yellow

Sulfate Ions

1. Add dilute to sample.
2. Add Barium Chloride solution.
3. If sulfate is present we will see a white precipitate.
