Copper and concentrated sulfuric acid.
The ionic equation of the reaction is: Cu + 2H2 SO4 (concentrated) CuSO4 + SO2 + 2H2O.
The reaction of copper and concentrated sulfuric acid belongs to the reduction reaction of oxygen shed burial.
Because the chain belt is liquid molded concentrated sulfuric acid has strong oxidizing properties, it can oxidize inactive copper.

The ionic equation for the reaction of sodium with copper sulfate solution is: 2Na + 2H2O ==2Na+ +2OH- +H2. cu2+ +2oh- =cu(oh)2↓。
Merge as Cu2+ +2Na + 2H2O ==Cu(OH)2 2Na+ +H2.
This response is actually prioritized and carried out in two steps. Sodium and copper sulfate solution: first, sodium first reacts with water to redox to generate sodium hydroxide, and then sodium hydroxide and copper sulfate undergo metathesis reaction to generate copper hydroxide and sodium sulfate.
When sodium reacts with copper sulfate solution, sodium first reacts with water for redox reaction, oxidant HO, oxidized element Na, oxidation product NaOH to generate NaOH and hydrogen. The chemical equation of the reaction is: 2Na+2H O=2NaOH+H.
Next, NaOH undergoes a metathesis reaction with copper sulfate. The chemical equation of the reaction is CuSO2NaOH Cu(OH)NaSO, which produces copper hydroxide and sodium sulfate.
The general equation for the reaction of sodium metal with copper sulfate solution is: 2Na+Cu 2H O=2Na Cu(OH) H. The phenomenon of chemical reaction between sodium metal and copper sulfate solution:
The sodium metal melts into bright balls, swims around on the water surface, makes a "hissing" sound, and colorless and odorless gas is generated, and at the same time, there is a blue flocculent precipitate in the reaction vessel.
