Substances are given: calcium oxide, calcium hydroxide, hydrochloric acid, sulfur (IV) oxide, zinc oxide, aluminum hydroxide. Which of these substances will interact with each other? Write down the reaction equations.
Possible reactions.
CaO + 2HCl = CaCl2 + H2O.
CaO + SO2 = CaSO3.
Ca (OH) 2 + 2HCl = CaCl2 + 2H2O.
Ca (OH) 2 + SO2 = CaSO3 + H2O.
2HCl + ZnO = ZnCl2 + H2O.
3HCl + Al (OH) 3 = AlCl3 + 3H2O.
SO2 + ZnO = ZnSO3.
