Answer 1

1) AlCl3+3NaOH==Al(OH)3+3NaCl

2) 2Al(OH)3 = Al2O3 +3H2O

3) Al2O3 + 3H2SO4 = Al2(SO4)3 + 3H2O 

4) Al2(SO4)3 + 6H2O = 2Al(OH)3↓ + 3H2SO4

5) Al(OH)3 + HCl=Al(OH)2Cl + H20 

 

Answer 2

Chemical Reactions in the Given Sequence

The given sequence "AlCl3 - Al(OH)3 - Al2O3 - Al2(SO4)3 - Al(OH)3 - Al(OH)2Cl" appears to represent a series of chemical reactions involving aluminum and various compounds. Let's break down the reactions step by step.

1. AlCl3 - Aluminum chloride (AlCl3) is a compound formed by the reaction of aluminum with chlorine. It is a white or pale yellow solid that can undergo hydrolysis in water to form various species, including aluminum hydroxide.

2. Al(OH)3 - Aluminum hydroxide (Al(OH)3) is a gelatinous solid formed by the hydrolysis of aluminum compounds, including aluminum chloride. It is amphoteric, meaning it can act as both an acid and a base.

3. Al2O3 - Aluminum oxide (Al2O3) is a compound formed by the combination of aluminum and oxygen. It is commonly known as alumina and is used in various industrial processes, including the production of aluminum metal.

4. Al2(SO4)3 - Aluminum sulfate (Al2(SO4)3) is a chemical compound that forms when aluminum oxide reacts with sulfuric acid. It is used in water treatment, paper production, and as a mordant in dyeing.

5. Al(OH)3 - Aluminum hydroxide (Al(OH)3) is formed again, possibly indicating a reversible reaction or a separate occurrence of aluminum hydroxide formation.

6. Al(OH)2Cl - Aluminum hydroxychloride (Al(OH)2Cl) is a group of specific aluminum salts used as coagulants in water treatment processes.

Conclusion

The given sequence represents a series of chemical reactions involving aluminum and various compounds, including the formation of aluminum hydroxide, aluminum oxide, aluminum sulfate, and aluminum hydroxychloride. Each compound in the sequence represents a specific chemical transformation involving aluminum and other elements or compounds.
