如图为一“铁链”图案,小明在图案上分别写了H2、CO2、Na2O、NaCl、FeCl3五种物质,图中相连的两种物质均可归属为一类,相交部分A、B、C、D为其相应的分类依据代号。请回答下列问题:                                                                                                                              

(1)请将分类依据代号填入括号内:               两种物质都不是电解质                                                                                                                       

(2)用洁净的烧杯取少量蒸馏水,用酒精灯加热至沸腾,向烧杯中逐滴加入1 mol·L-1图中某物质M的水溶液,继续煮沸可制得一种红褐*液体。                                                                                                                    

①物质M的化学式为　　　　　　　　　　　　。                                                                                                                  

②*所制得的红褐*液体是胶体的实验*作是                                 　。                                                                                                                                   

（3）下图是硫*试剂瓶标签上的内容：                                                                                                                           

①该硫*的物质的量浓度是______         __mol·L－1。                                                                                                           

②某化学兴趣小组进行硫**质的实验探究时，上述硫*进行稀释的实验*作为                                                                                                                 

                                                                              。

【回答】

(1)A　(2)①FeCl3　②用一束光照*烧杯中的液体,若能产生丁达尔效应,则*生成了Fe(OH)3胶体                                                                                                                           

（3）①18.4 mol·L－1  ②将浓硫*沿着烧杯壁缓慢注入水中，同时用玻璃棒快速搅拌
