Dear Meimei,
    Thank your for your last letter. I have been here more than a month   1   I left Shanghai for Tokyo. Now,
let me tell you   2   about Tokyo. I enjoy   3   all places of great interest here very much. But it is difficult for
me to find my way around the city.   4   Tokyo, only the important streets have names, and houses are
numbered by age (按年代编号).   5  , when the first house was built in a place, it was Number One, and the
second was Number Two. Sometimes, the second house may be over a kilometer   6   from the first house.
Most of the people here are   7   to tell other persons ways. One man even drew a   8   for me when I asked
him how I could   9   the station. How strange it is! Please write to  10  soon.
                                                                                                                                           Yours, 
                                                                                                                                           Fangfang

实验题

（18分）某校化学兴趣小组为研究Cu与浓硫酸反应并制备少量硫酸铜，进行如下实验。

该小组同学在实验中发现使用教材所提供的铜和浓硫酸反应的实验装置不仅安全性差而且易造成环境污染。经过同学们的讨论以及老师的指导，该小组设计了如图所示的装置并进行实验。

请回答：

（1）请写出长导管B的作用                                       （只写一点就可）；

(2)写出检查该装置气密性的方法                                              。

（3）D、E试管中CCl4的作用                   。

（4）写出A中发生反应的化学方程式并标出电子转移的方向与数目                  

                                                  

（5）对试管A进行加热，发现E试管中有气泡逸出，品红溶液很快褪色，但最终未见D试管中氢氧化钡溶液出现浑浊，为探究D试管中未出现浑浊的原因，该小组同学在化学手册中只查阅到下列物质常温下的溶解度数据：

物质溶解度（g/100水）物质溶解度（g/100水）
Ca（OH）20.173Ba(OH)23.89
CaCO30.0013BaSO30.016
Ca（HCO3）216.60  
请你应用类比研究方法帮他们预测D试管未出现浑浊的原因：                 。

（6）为验证D试管中溶液的组成，进行了下列实验，请你帮助完成下列实验报告：

实验方案现象
方案1：取少量溶液于试管中，加入稀盐酸，加热，用①检验产生的气体。②               
方案2：取少量溶液于试管中，加入③       溶液并观察现象。④
