硫和氧化铜反应的实验探究

Experiment Inquiry on Reaction of Sulfur and Copper Oxide

硫能和金属单质、非金属单质、强碱、强氧化性酸发生反应,表现出一定的氧化性和还原性。氧化铜是一种氧化性较强的金属氧化物,在一定的条件下,硫和氧化铜能发生反应生成氧化亚铜和二氧化硫,氧化亚铜和硫蒸气在高温下还能继续反应生成硫化亚铜和二氧化硫。

Sulfur can react with metal,nonmetal,strong alkali and strong oxidizing acids and show a certain level of oxidbillity and reducibility.Copper oxide is a kind of metallic oxide with strong oxidation.Under certain conditions,the reaction between sulfur and copper oxide can generate cuprous oxide and sulfur dioxide.When cuprous oxide reacts with sulfur vapor at high temperature,cuprous sulfide and sulfur dioxide can be produced.
