5.3 结论总结 通过以上实验验证分析,铜与浓硫酸反应产生黑色沉淀物,可能存在CuO,一定存在 Cu2S和CuS,同时铜与浓硫酸反应是否产生黑色沉淀,还与温度有密切关系,低温时易产 生黑色沉淀物,主要发生以下两个反应: Cu+H2S04(浓)尘CuO+SO?f+H:0 ①5Cu+4H2S04(浓):垒Cu2S l+3CuS04+4H二0 ②其中,反应①产生...
H2SO4(aq)→2H+(aq)+ SO42-(aq) CuSO4(aq)→ Cu2+(aq)+ SO42-(aq) Cu(s)+2H+(aq)+ SO42-(aq)= Cu2+(aq)+ SO42-(aq)+ H2(g) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ...
H2SO4 + Cu = Cu(SO4) + H2 is a Single Displacement (Substitution) reaction where one mole of aqueous Sulfuric Acid [H2SO4] and one mole of solid Copper [Cu] react to form one mole of aqueous Cupric Sulfate [Cu(SO4)] and one mole of Dihydrogen [H2] gasReaction...

I took a small sample of it, added like 5 drops of 96% H2SO4, and there it was, white precipitate in a brown solution, the CuI and I2. There's little to no doubt that the ammonia in solution plays a role in the formation of the green precipitate, and neutralizing it with an ac...
