Question

How do you separate Sodium chloride, Iodine crystals, and Copper[II] oxide powder?

Answer 1

To separate Sodium chloride, Iodine crystals, and Copper[II] oxide powder, dissolve the Sodium chloride and filter it, then use acid to dissolve the Copper[II] oxide powder and filter the solution.

Step-by-step explanation:

To separate Sodium chloride, Iodine crystals, and Copper[II] oxide powder, you can use a combination of solubility, precipitation, and filtration techniques.

1. Add water to the mixture to dissolve the Sodium chloride.
2. Filter the mixture to separate out the undissolved Iodine crystals.
3. Evaporate the filtrate to recover the Sodium chloride.
4. Perform a reaction with acid to dissolve the Copper[II] oxide powder and then filter the solution to separate it from other remaining substances.
