Question

Al2O3 - Al2(SO4)3 - Al(OH)3 - Al2O3

Answer 1

Al₂O₃ → Al₂(SO₄)₃→ Al(OH)₃ → Al₂O₃

Al₂O₃+ 3H₂SO₄ = Al₂(SO₄)₃+3H₂O

Al₂(SO₄)₃ + 6NaOH= 2Al(OH)₃  + 3Na₂SO₄

2Al(OH)₃ = Al₂O₃ + 3H₂O

Answer 3

The sequence you've provided represents different chemical compounds involving aluminum (Al) and oxygen (O), as well as sulfur (S) and hydrogen (H). Let's identify and describe each compound:

1. Al2O3: This is aluminum oxide, commonly known as alumina. It is a compound composed of two aluminum atoms (Al) bonded to three oxygen atoms (O). Aluminum oxide is an important industrial material and is widely used in various applications, including as a raw material in the production of aluminum metal, ceramics, and abrasives.

2. Al2(SO4)3: This compound is aluminum sulfate. It consists of two aluminum ions (Al) combined with three sulfate ions (SO4). Aluminum sulfate is often used as a flocculating agent in water treatment, and it also has applications in the paper industry and as a mordant in dyeing.

3. Al(OH)3: This is aluminum hydroxide, a compound composed of one aluminum ion (Al) and three hydroxide ions (OH). It is commonly found as a gel-like precipitate in solutions of aluminum salts and is used in various pharmaceuticals, antacids, and as a flame retardant.

4. Al2O3: As mentioned before, this is aluminum oxide (alumina), already described above.

To summarize:

• Al2O3: Aluminum oxide (Alumina)
• Al2(SO4)3: Aluminum sulfate
• Al(OH)3: Aluminum hydroxide (Gibbsite)
• Al2O3: Aluminum oxide (Alumina) [repeated]

Each of these compounds has distinct properties and applications in various industries.
