某化学探究小组为了验证铁、铜、锌、银的金属活动性顺序，设计了如下实验方案：

①将铁片加入到稀盐酸中；

②将铜片加入到硝酸银溶液中；

③将锌片加入到稀盐酸中；

④将金属片X加入到Y中．

（该方案中所有金属均已打磨，且形状、大小以及稀盐酸的溶质质量分数均相同）

（1）写出①中反应的化学方程式：                            ；

（2）通过上述实验，可以判断锌的金属活动性比铁强，依据的现象是                        ；

（3）要得出这四种金属的活动性顺序，如果④中Y表示硫酸铜溶液，则X表示的一种金属是   ；如果X表示铜，则Y表示的一种溶液是     。
