Copper metal dissolves in hot concentrated sulphuric acid to form solutions containing the aquated Cu(II) ion together with hydrogen gas, H2. As a mineral, it is known as tenorite.It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds. But nitrogen in nitric acid is reduced from +5 to +4 by producing nitrogen dioxide which is a brown color and acidic gas. Copper does not react with water. Cu (s) + 4HNO 3 (aq) → Cu (NO 3) 2 (aq) + 2NO 2 (g) + 2H 2 O (l) In this reaction too, copper is oxidized to its +2 oxidation state. If the acid has not been hot enough, excess acid can co-exist with copper oxide. The blue copper(II) hydroxide decomposes upon heating to form black copper(II) oxide and water vapor (see Equation 3). In practice, the Cu(II) is present as the complex ion [Cu(OH2)6]2+. H2SO4 + MgO ---> H2O + MgSO4 .This is a balanced equation . 2Cu + C ------> 2Cu + CO2 Still have questions?
