某研究性学习小组在网上收集到如下信息:Fe( NO3)3溶液可以蚀刻银,制作美丽的银饰。他们对蚀刻银的原因进行了如下探究:

【实验】制备银镜,并与Fe( NO3)3溶液反应,发现银镜溶解。

(1)下列有关制备银镜过程的说法正确的是_______。

a.边振荡盛有2%的AgNO3溶液的试管,边滴入2%的氨水,至最初的沉淀恰好溶解为止

b.将几滴银氨溶液滴入2 mL乙醛中

c.制备银镜时,用酒精灯的外焰给试管底部加热

d.银氨溶液具有较弱的氧化性

e.在银氨溶液配制过程中,溶液的pH增大

【提出假设】

假设l:Fe3+具有氧化性,能氧化Ag。

假设2:Fe(NO3)3溶液显酸性,在此酸性条件下NO3-能氧化Ag。

【设计实验方案,验证假设】

(2)甲同学从上述实验的生成物中检验出Fe2+,验证了假设1成立。请写出Fe3+氧化Ag的离子方程式:_______________。

(3)乙同学设计实验验证假设2,请帮他完成下表中内容(提示:NO3-在不同条件下的还原产物较复杂,有时难以观察到气体产生)。

【思考与交流】

(4)甲同学验证了假设1成立,若乙同学验证了假设2也成立,则丙同学由此得出结论:Fe( NO3)3溶液中的Fe3+和NO3-都氧化了Ag。你是否同意丙同学的结论,并简述理由:___________。
