        Some members of an International Voluntary Organization (国际志愿组织) arrived at a small village of an
African country.
        The villagers lived in small houses, which were built with wood and leaves. There was no school or
hospital. The villagers didn't know how to grow crops. They only went to kill some wild animals and pick some
fruits in the mountains as their food. The volunteers (志愿者) came here to help the village kids. They brought
with them many textbooks and some medicine. They taught the kids how to play volleyball and also tried to learn
their language so that they could talk with the kids better.
         Because of their hard work, the International Voluntary Organization gave the villagers the money to carry
electricity to the village. When the lights in every house were shining, the villagers were very excited. They called
them "the little suns". Then, they held a party to choose some lucky men who would invite the volunteers to go
to their homes to see the beautiful night together with their families.

题型：填空题

如下图装置所示，C、D、E、F、X、Y都是惰性电极，甲、乙中溶液的体积和浓度都相同（假设通电前后溶液体积不变），A、B为外接直流电源的两极。将直流电源接通后，F极附近呈红色。

请回答：

（1）B极是电源的___________ ，一段时间后，甲中溶液颜色 __________，丁中X极附近的颜色逐渐变浅，Y极附近的颜色逐渐变深，这表明___________ ，在电场作用下向Y极移动。

（2）若甲、乙装置中的C、D、E、F电极均只有一种单质生成时，对应单质的物质的量之比为 ______________。

（3）现用丙装置给铜件镀银，则H应该是______________ （填“镀层金属”或“镀件”），电镀液是___________ 溶液。当乙中溶液的pH是13时（此时乙溶液体积为500mL），丙中镀件上析出银的质量为_____________ ，甲中溶液的pH _____________（填“变大”、“变小”或“不变”）。

（4）若将C电极换为铁，其他装置都不变，则甲中发生总反应的离子方程式是______________ 。
