Answer 1

Answer on Question #75283, Chemistry / Inorganic Chemistry

1. Reaction showing acidic behaviour of sulphur dioxide:

$$\mathrm {S O} _ {2} + \mathrm {K O H} \rightarrow \mathrm {K} _ {2} \mathrm {S O} _ {3} + \mathrm {H} _ {2} \mathrm {O}$$

2. Reaction depicting the sulphonation by $\mathrm{H}_2\mathrm{SO}_4$

$$2 \mathrm {H} _ {2} \mathrm {S O} _ {4} \rightarrow \mathrm {S O} _ {3} + \mathrm {H} _ {3} \mathrm {O} ^ {+} + \mathrm {H S O} _ {4} ^ {+}$$

3. Reactions of lead chambers during the manufacture of H2SO4 by Lead Chamber process

$$2 \mathrm {O N O S O} _ {2} \mathrm {O H} + \mathrm {H} _ {2} \mathrm {O} \rightarrow 2 \mathrm {H} _ {2} \mathrm {S O} _ {4} + \mathrm {N O} + \mathrm {N O} _ {2}$$ $$\mathrm {S O} _ {2} + \mathrm {N O} _ {2} + \mathrm {H} _ {2} \mathrm {O} \rightarrow \mathrm {H} _ {2} \mathrm {S O} _ {4} + \mathrm {N O}$$

4. Reaction distinguishing between peroxomonosulphuric acid and peroxodisulphuric acid

$$5 \mathrm {H} _ {2} \mathrm {S O} _ {3} (\mathrm {O} _ {2}) + 2 \mathrm {C} _ {6} \mathrm {H} _ {6} = 5 \mathrm {S O} _ {2} + 2 \mathrm {C O} _ {2} + 1 0 \mathrm {C} + 1 1 \mathrm {H} _ {2} \mathrm {O}.$$

5. Reduction reaction of $\mathrm{H}_2\mathrm{O}_2$ with chlorine

$$\mathrm{H_2O_2} + \mathrm{Cl_2} \rightarrow \mathrm{O_2} + 2\mathrm{HCl}$$
