Substances are given: potassium oxide, hydrochloric acid, sodium, calcium hydroxide, water. Which of these substances will interact with sulfuric acid? Write the equations of the corresponding reactions

In the task we were given chemicals: potassium oxide – K2O, sulfuric acid – H2SO4, sodium – Na, calcium hydroxide – Ca (OH) 2, water – H2O. Consider what chemical reactions can occur between them:

Potassium oxide reacts chemically with sulfuric acid and forms a potassium sulfide salt and water is released.

K2O + H2SO4 = K2SO4 + H2O
A chemical reaction takes place between substances such as sodium and sulfuric acid. As a result of the reaction, sodium sulfate salt is obtained and hydrogen gas is released.

Na + H2SO4 = Na2SO4 + H2
Calcium hydroxide base chemically reacts with sulfuric acid to obtain calcium sulfate salt and water.

Ca (OH) 2 + H2SO4 = CaSO4 + 2 H2O.
