为验证卤素单质氧化性的相对强弱,某小组用右图所示装置进行试验(夹持仪器已略去,气密性已检验)。试验过程:

I.打开弹簧夹,打开活塞a,滴加浓盐酸。
II.当B和C中的溶液都变为黄色时,夹紧弹簧夹。
III.当B中溶液由黄色变为棕色时,关闭活塞a。
IV.……
试回答下列问题:
(1)A中产生                                                                                                         色气体,其结构式是                 
(2)能使湿润的淀粉—KI试纸变蓝的气体是                                                                 
(a) Cl2 (b) N2O4 (c) I2蒸气 (d) SO2 (e) O3 (f) CO2
(3)滴加浓盐酸前,分液漏斗首先要                                                                                                                      
(4)过程III实验目的是                                                                                                                                                                                                                                                            
(5)A中产生氯气的离子方程式为                                                                                                                                                                                                                                                       
(6)B中浸有NaOH溶液的棉花作用是                                                                                               ,写出反应的离子方程式
