补充资料：银氨溶液
化学式：ag(nh3)2oh
人教版高中化学：
※配置方法
1.准备试管：在试管里先注入少量naoh溶液，振荡，然后加热煮沸。把naoh倒去后，再用蒸馏水洗净备用。
2.配置溶液：在洗净试管中，注入1ml agno3溶液，然后逐滴加入氨水，边滴边振荡，直到最初生成的沉淀刚好溶解为止。
※银镜反应
沿试管壁滴入三滴乙醛稀溶液，把试管放在盛有热水的烧杯里，静置几分钟。不久，可以观察到试管内壁上附着了一层光亮如镜的金属银。
※注意事项：
1.银镜反应的成败关键之一，是所用的仪器是否洁净。
2.配制银氨溶液时，应防止加入过量的氨水。银氨溶液必须随配随用，不可久置。
3.实验完毕，试管内的银氨溶液要及时处理，先加入少量盐酸，倒去混和液后，再用少量稀硝酸洗去银镜，并用水洗净。
