关注 简单点: 铝的金属性比同周期的Na和Mg弱，与水反应时失电子能力比那两个弱以至于直接与水反应反应限度极小，认为不发生反应 需要有强碱加入，消耗氢氧化铝来使平衡正移，增大反应限度，使其在宏观上可以发生 编辑于 2024-08-17 18:01 赞同 1 条评论 分享 收藏 喜欢 收起 JASON HFLSer 关注 4 人 赞同了该回答 这个反应是可逆反应，你把铝放到水里，多多少少总会反应一点的，但是沉淀一般是看不见的。 如果加了NaOH，情况就不同了——生成的Al（OH）3被消耗，据勒夏特列原理，平衡正移。 所以宏观上表现为能与NaOH溶液反应。 发布于 2024-08-18 22:05 赞同 4 添加评论 分享 收藏 喜欢 收起 好在有你 Web题目.
