Question

6) S-> SO2 -> H2S03 —> Na2S03;​

Answer 1

S + O₂ →t→ SO₂

SO₂ + H₂O → H₂SO₃

H₂SO₃ + 2NaOH → Na₂SO₃ + 2H₂O

Answer 2

The given sequence represents a chemical reaction pathway, starting with sulfur (S) and ending with sodium sulfite (Na2SO3). Let's break down the reactions step by step:

1. S -> SO2: In this reaction, sulfur (S) is oxidized to form sulfur dioxide (SO2). This is a combustion reaction where sulfur reacts with oxygen to produce SO2.

2. SO2 -> H2SO3: Sulfur dioxide (SO2) can dissolve in water to form sulfurous acid (H2SO3). This is an acidic solution.

3. H2SO3 -> Na2SO3: Sulfurous acid (H2SO3) can react with sodium hydroxide (NaOH) to produce sodium sulfite (Na2SO3) and water (H2O).

So, the overall reaction pathway is as follows: S -> SO2 -> H2SO3 -> Na2SO3

This sequence represents the transformation of elemental sulfur into sodium sulfite through a series of chemical reactions involving oxidation and neutralization.
