Substances are given calcium oxide calcium hydroxide hydrochloric acid sulfur oxide 4, zinc oxide, aluminum hydroxide. Which of these substances will interact with each other?

Classes of substances are given: bases (react with acidic oxides, acids); oxides (basic – react with acids and acidic oxides; acidic – react with bases); amphoteric oxides and hydroxides (react with both bases and acids).

Ca (OH) 2 + SO2 = CaSO3 + H2O.

Ca (OH) 2 + 2HCl = CaCl2 + 2H2O.

Ca (OH) 2 + 2Al (OH) 3 = Ca [Al (OH) 4] 2.

Ca (OH) 2 + ZnO = CaZnO2 + H2O.

CaO + 2HCl = CaCl2 + H2O.

CaO + SO2 = CaSO3.

CaO + ZnO = CaZnO2

ZnO + SO2 = ZnSO3

3ZnO + 2Al (OH) 3 = Al2 (ZnO2) 3 + 3H2O

ZnO + 2HCl = ZnCl2 + H2O

Al (OH) 3 + 3HCl = AlCl3 + 3H2O.

2Al (OH) 3 + SO2 = Al2 (SO3) 3 + 3H2O.

Zinc oxide is amphoteric, so it will react with both bases and acids.

Aluminum hydroxide – amphoteric, will react with acids and bases, with basic oxides.
