Question

Show the complete schematic diagram (9 steps) showing the reagents/s used, color of solution/precipitate formed and chemical formula/s of compounds formed in the separation of Group I ions/elements.

Example: starting point: Solution containing Group lions containing 15 drops of either the Group I known or the General Unknown
Step 1 - Step 2 - precipitate
Step 3 - supernatant liquid
Step 4 - Step 5 - precipitate
Step 6 - supernatant liquid
Step 7 - Step 8 - precipitate
Step 9 - supernatant liquid​

Answer 1

The complete schematic diagram for the separation of Group I ions/elements involves several steps including adding specific reagents, the formation of precipitates, and separating the precipitate from the supernatant liquid. The process is repeated as necessary to achieve the desired separations.

Step-by-step explanation:

In the separation of Group I ions/elements, several steps are involved.

1. Step 1: Start with a solution containing Group I ions.
2. Step 2: Add a specific reagent to the solution. A precipitate will form if there is a combination of cations and anions that can become insoluble.
3. Step 3: Separate the precipitate (formed in Step 2) from the solution by filtration. The precipitate is collected, and the supernatant liquid is obtained.
4. Step 4: Add another reagent to the supernatant liquid obtained in Step 3. This will cause further precipitation of specific ions.
5. Step 5: Separate the newly formed precipitate from the supernatant liquid by filtration. Collect the precipitate and obtain the supernatant liquid.
6. Step 6: Repeat Steps 4 and 5 as necessary until all the desired separations are achieved.
7. Step 7: After the final separation, collect the precipitate and obtain the supernatant liquid.
8. Step 8: Repeat the process of adding a reagent to the supernatant liquid, causing further precipitation
9. Step 9: After each separation, collect the precipitate and obtain the supernatant liquid.
