| February 16, 2021 | education

Let us write down the reaction equation for the interaction of concentrated sulfuric acid H₂SO₄ with copper Cu.
H₂SO₄ conc. + Cu = SO₂ + CuSO₄ + 2H₂O.
Thus, as a result of this reaction, copper reduces concentrated sulfuric acid to sulfur dioxide. This gas is also called sulfur oxide and sulfur dioxide. Its chemical formula is SO₂. In addition, you should pay attention to the fact that this colorless gas has a pungent smell of a burning match, as well as the fact that it is poisonous, as a result of which the specified reaction must be carried out under traction.
In addition, as a result of this reaction, the copper salt of sulfuric acid CuSO₄ is formed. This salt is a non-volatile odorless substance, it is a white powder.
Also, as a result of this reaction, water is formed.
