比较金属活动性强弱的方法有多种,既可以利用金属与酸、金属与金属化合物反应来判断,也可以利用金属与氧气反应来判断,具体选用何种方法必须因题而定。一、根据金属与氧气反应的难易和剧烈程度判断金属的化学活动性例1考古研究与化学密不可分。“南海一号”古沉船于2007年被成功打捞出水,考古专家发现在打捞出的文物中“鎏金龙纹金手镯”光彩夺目、完好无损;铜镜表面有铜锈;铁器则锈迹斑斑或荡 There are many ways to compare the strength of metal activity, both metal and acid, metal and metal compounds to determine the reaction can also be used to determine the reaction of metal and oxygen, the specific choice of which method must be due to the problem. First, according to the metal reaction with the ease and severity of the metal to determine the chemical activity of Example 1 Archeology and chemistry are inseparable. “The South China Sea One ” Ancient sunken ship was successfully salvaged water in 2007, archaeologists found in the artifacts retrieved from the “Golden dragon gold bracelet ” dazzling, intact; copper mirror surface with copper; iron is rust Stained or swirled
