Answer 1

Chemical Transformations:

The given chemical transformations involve the conversion of AlCl3 to Na[Al(OH)4]+. Let's break down each step:

1. AlCl3 to Al(OH)3: - AlCl3 is reacted with water (H2O) to form Al(OH)3 and HCl. - The reaction is as follows: AlCl3 + 3H2O -> Al(OH)3 + 3HCl [[1]].

2. Al(OH)3 to Al2O3: - Al(OH)3 can be dehydrated to form Al2O3 (aluminum oxide) through a heating process. - The reaction is as follows: 2Al(OH)3 -> Al2O3 + 3H2O [[2]].

3. Al2O3 to Na[Al(OH)4]: - Al2O3 reacts with NaOH (sodium hydroxide) to form Na[Al(OH)4]. - The reaction is as follows: Al2O3 + 2NaOH + 3H2O -> 2Na[Al(OH)4] [[3]].

4. Na[Al(OH)4] to Al2(SO4)3: - Na[Al(OH)4] reacts with H2SO4 (sulfuric acid) to form Al2(SO4)3 and NaOH. - The reaction is as follows: 2Na[Al(OH)4] + 3H2SO4 -> Al2(SO4)3 + 6H2O + 2NaOH [[4]].

5. Al2(SO4)3 to Al(OH)3: - Al2(SO4)3 can be hydrolyzed with water to form Al(OH)3 and H2SO4. - The reaction is as follows: Al2(SO4)3 + 6H2O -> 2Al(OH)3 + 3H2SO4 [[5]].

6. Al(OH)3 to AlCl3: - Al(OH)3 can react with HCl to form AlCl3 and water (H2O). - The reaction is as follows: Al(OH)3 + 3HCl -> AlCl3 + 3H2O [[6]].

7. AlCl3 to Na[Al(OH)4]+: - AlCl3 can react with NaOH to form Na[Al(OH)4] and HCl. - The reaction is as follows: AlCl3 + 3NaOH -> Na[Al(OH)4] + 3HCl [[7]].

Summary of Chemical Transformations:

The complete chain of chemical transformations is as follows: AlCl3 -> Al(OH)3 -> Al2O3 -> Na[Al(OH)4] -> Al2(SO4)3 -> Al(OH)3 -> AlCl3 -> Na[Al(OH)4]+.
