Question

SO2 → Н2SO3 → Al2(SO3)3 → Al(OH)3

Answer 1

SO2+H2O → H2SO3

3 H2SO3 + Al2O3 → 3 H2O + Al2(SO3)3

Al2(SO3)3 + 6 NaOH → 2 Al(OH)3 + 3 Na2SO3

Answer 2

It seems like you've provided a sequence of chemical reactions involving different compounds. Let me break down each step for you:

1. SO2 (Sulfur Dioxide): Sulfur dioxide is a colorless gas with the chemical formula SO2. It is a common air pollutant and is produced by the combustion of sulfur-containing fuels, among other processes.

2. H2SO3 (Sulfurous Acid): Sulfur dioxide (SO2) can dissolve in water to form sulfurous acid (H2SO3). The reaction can be represented as follows:

   SO2 + H2O → H2SO3

3. Al2(SO3)3 (Aluminum Sulfite): Sulfurous acid (H2SO3) can react with aluminum hydroxide (Al(OH)3) to form aluminum sulfite (Al2(SO3)3). The balanced chemical equation for this reaction is:

   2 Al(OH)3 + 3 H2SO3 → Al2(SO3)3 + 6 H2O

4. Al(OH)3 (Aluminum Hydroxide): Aluminum sulfite (Al2(SO3)3) can react with water (H2O) to produce aluminum hydroxide (Al(OH)3):

   Al2(SO3)3 + 6 H2O → 2 Al(OH)3 + 3 H2SO3

These reactions show how sulfur dioxide can eventually lead to the formation of aluminum hydroxide through a series of chemical reactions involving sulfurous acid and aluminum sulfite intermediates. It's important to note that these reactions may require specific conditions and concentrations of reactants to proceed effectively.
