现代生活中,光污染已经给人类的生活和身体带来了极大的危害。据光学专家研究,镜面建筑物玻璃的反射光比阳光照射更强烈,其反射率高达82%90%。长时间在白色光亮污染环境下工作和生活的人,容易导致视力下降,产生头昏目眩、心悸、情绪低落等症状,影响正常生活。某校在草地上立了一个金属材质的水滴造型,寓意滴水之恩,光亮如镜。但其超强的反射性直接影响了众多办公室。现有化学实验小组欲对其进行适当的腐蚀化处理,请选出腐蚀速度最快的方法(    

A.将水滴造型与锌块相连

B.将水滴造型与电源的负极相连

C.将水滴造型与电源的正极相连

D.进行多次人工降雨

答案

【答案】C

【解析】

试题分析:A、将水滴造型与锌块相连构成原电池;B、将水滴造型与电源的负极相连,作阴极,被保护;C、将水滴造型与电源的正极相连,作阳极,即可腐蚀;D、进行多次人工降雨,腐蚀最慢,所以腐蚀速度最快的是与电源的正极相连作阳极,答案选C

考点:考查金属的电化学腐蚀
