Given acid H2SO3. The oxidation state of oxygen is constant, equal to -2. The oxidation state of hydrogen is constant, equal to +1. You need to know the oxidation state of sulfur. Let’s make the equation: 1 × 2 + X × 1 + (-2) × 3 => 2 + X-6 => X = 6-2 => X = 4. Check: cons (O) = – 6; pluses (H, S) = 2 + 4 = 6. 6 = -6. So they decided correctly.
Answer: The oxidation state of hydrogen is +1. Sulfur oxidation state: +4. Oxygen oxidation state: -2.
