Question
Prepare a written copy of the complete separation scheme for a solution that contains Ag+, Fe3+, Cr3+, Ni2+, Zn2+, and Ba2+.
Make sure that your separation scheme includes:
- separation of each ion into its own individual sample AND precipitation BEFORE a confirmation test is done
- all phases and visible colors, if applicable
- reagents and conditions necessary to carry out each step
- balanced equations, including phases, for each step
Transcribed Image Text:Data for the preliminary tests for each metal are included below. If a precipitate was
formed, the color was noted. Precipitates that dissolved were also noted. If no data is
included, the ion did not precipitate.
