Molecular Equations for the Given Transformation:

To carry out the transformation according to the given scheme: sodium iodide -> hydrogen iodide -> aluminum iodide -> potassium iodide -> potassium nitrate, we need to write the molecular equations for each step.

1. Sodium iodide to hydrogen iodide: - The reaction equation is: 2 NaI + H2SO4 → 2 HI + Na2SO4 [[1]].

2. Hydrogen iodide to aluminum iodide: - The reaction equation is: 2 HI + Al → 2 AlI3 + H2 [[2]].

3. Aluminum iodide to potassium iodide: - The reaction equation is: 2 AlI3 + 6 K → 2 Al + 6 KI [[3]].

4. Potassium iodide to potassium nitrate: - The reaction equation is: 2 KI + H2O2 → 2 KOH + I2 (iodine is liberated) - Then, 2 KOH + HNO3 → KNO3 + H2O [[4]].

Please note that these equations represent the molecular reactions involved in the transformation. The actual reaction conditions and specific reagents may vary depending on the experimental setup.
