CHM110H5 Lecture Notes - Lecture 1: Barium Chloride, Sodium Bromide, Transition Metal
Document Summary
In this experiment, nine solutions of a known composition were provided, along with the same nine solutions in a group of unidentified bottles labelled 1 through 9. Given the composition of each solution, as shown below, it was required to determine the contents of each numbered solution. To do so, all other solutions were used as reagents, and other techniques such as the solubility of salts, colors, acid-base reactions, and more were used to aid in identification. 6 m naoh 3 m nh4cl 1 m nabr. 0. 5 m na2s 0. 3 m na2so4 0. 5 m kclo3. 0. 2 m bacl2 0. 2 m kio3 0. 1 m agno3. By mixing a small amount of each unidentified solution in test tubes, around ten drops of each, combinations of each solution were made. To follow, observations following the reactions were made and recorded in the table on page 42 of the course manual.
