    青花瓷化学版

    我们以这个看过后不免让人感动的化学老师作为实验组,如视频1-1所示。
    与模型对照组比较具有显著差异……

    ……
    色蓝紫 状的沉淀 跃然试管底    铜离子 遇氢氧根 再也不分离
    当溶液 呈金黄色 因为铁三价    浅绿色二价亚铁把人迷
    电石偷偷去游泳 生成乙炔气     点燃后变乙炔焰 高温几千几
    逸散那二氧化碳  石灰水点缀白色沉底
    (苯系列)
    苯遇高锰酸钾 变色不容易     甲苯上加硝基 小心TNT
    在苯中的碘分子紫色多美丽    就为萃取埋下了伏笔
    (电化学)
    电解池电解质 通电阴阳极     化合价有高低 电子来转移
    精炼了铜铁锌锰镍铬铝银锡    留下阳极泥
    (浓酸稀释)
    稀释那浓硫酸 注酸入水里      沿器壁慢慢倒 搅拌手不离
    浓酸沾皮肤立即大量水冲洗     涂抹上碳酸氢钠救急
    (生产实际)
    甘油滋润肌肤 光滑又细腻     熟石灰入土地 酸碱度适宜
    看酸红碱紫的试纸多么美丽    你眼带笑意 
     
    我们选用网上普遍流传的青花瓷化学版作为模型对照组,如视频1-2所示。
