In this task, you need to determine with which of the compounds diluted and concentrated sulfuric acid reacts.
Of these options, sulfuric acid reacts with zinc. Let’s write down the reaction equation.
Reaction with dilute sulfuric acid.
Zn + H2SO4 → ZnSO4 + H2.
When zinc reacts with sulfuric acid, the result is a zinc sulfate salt and hydrogen.
Reaction with concentrated sulfuric acid.
4Zn + 5H2SO4 = H2S + 4ZnSO4 + 4H2O.
When zinc reacts with sulfuric acid, the result is hydrogen sulfide, zinc sulfate salt and water.
