Question

Al→AlCl3→Al(OH)3→Al2O3→AlNaO2→Al2(SO4)3как решить эту цепочку?

Answer 1

2AL+6HCL=2ALCL3+3H2

2ALCL3+3H2O=2AL(0H)3+6HCL

2AL(0H)3=2AL2O3+3H2O

 

Answer 2

Solving the Chemical Reaction Chain

To solve the given chemical reaction chain, we can follow the sequence of reactions and products:

1. Al → AlCl3 2. AlCl3 → Al(OH)3 3. Al(OH)3 → Al2O3 4. Al2O3 → AlNaO2 5. AlNaO2 → Al2(SO4)3

Let's break down each step:

1. Al → AlCl3: - The reaction of aluminum (Al) with chlorine (Cl) results in the formation of aluminum chloride (AlCl3) [[5]](https://www.trims.edu.az/noduploads/book/quot-himiya-quot-kimya-fanni-uzra-9-cu-sinif-ucun-darslik-1597225611-433.pdf).

2. AlCl3 → Al(OH)3: - Aluminum chloride (AlCl3) reacts with water (H2O) to produce aluminum hydroxide (Al(OH)3) [[5]](https://www.trims.edu.az/noduploads/book/quot-himiya-quot-kimya-fanni-uzra-9-cu-sinif-ucun-darslik-1597225611-433.pdf).

3. Al(OH)3 → Al2O3: - Aluminum hydroxide (Al(OH)3) undergoes dehydration to form aluminum oxide (Al2O3).

4. Al2O3 → AlNaO2: - The reaction of aluminum oxide (Al2O3) with sodium hydroxide (NaOH) leads to the formation of sodium aluminate (AlNaO2).

5. AlNaO2 → Al2(SO4)3: - Sodium aluminate (AlNaO2) reacts with sulfuric acid (H2SO4) to yield aluminum sulfate (Al2(SO4)3).

By following these sequential reactions, we can solve the given chemical reaction chain.
