1. Let’s compose the equation of the reaction of sulfur combustion. Sulfur (IV) oxide is formed
S + O2 = SO2.
2.SO2 – acidic oxide, when interacting with water forms acid – sulphurous.
SO3 + H2O = H2SO3.
3. Let’s compose the equation of the reaction between sulfuric acid and sodium hydroxide. The reaction produces sodium sulfate and water.
H2SO3 + 2NaOH = Na2SO3 + 2H2O.
4.To obtain calcium sulfite from sodium sulfite, it is necessary to react with a soluble salt.
Ca (NO3) 2 + Na2SO3 = CaSO3 + 2NaNO3.
