From the list of formulas given – NaOH, H2O, PH3, MgCl2, H2SO4, CO2, Ba (OH) 2, HNO3, CH4, select the formulas of substances that interact with sulfur oxide (IV)
The following interacts with oxide series (IV) SO2:
1) Ba (OH) 2 (barium hydroxide) Ba (OH) 2 + SO2 = BaSO3 + H2O (barium sulfite is formed).
2) H2O (water) SO2 + H2O ⇄ H2SO3 (unstable sulfurous acid is formed).
3) NaOH (sodium hydroxide) 2NaOH + SO2 = Na2SO3 + H2O (sodium sulfite is formed).
