题目

Before she appeared on the reality show(真人秀) Britain’s Got Talent, Susan Boyle was just an ordinary middle-aged British woman. Now all this is going to change. She lives in a house with her cat Pebbles in a tiny Scottish town. Because of learning difficulties, she doesn’t have much education. But what she does have is a very good voice. As a kid, she sang in church and choirs and school plays. For a living, she sang at local pubs. When she took the stage on April 10th her hair was untidy and her clothes seemed just one step up from rags. The audience laughed at her. But the有A、B、C、D、E和F六瓶无色溶液，他们是中学化学中常用的无机试剂．纯E为无色油状液体；B、C、D和F是盐溶液，且他们的阴离子均不同．现进行如下实验：①A有刺激性气味，用沾有浓盐酸的玻璃棒接近A时产生白色烟雾；②将A分别加入其它五中溶液中，只有D、F中有沉淀产生；继续加入过量A时，D中沉淀无变化，F中沉淀完全溶解；③将B分别加入C、D、E、F中，C、D、F中产生沉淀，E中有无色、无味气体逸出；④将C分别加入D、E、F中，均有沉淀生成，再加入稀HNO3，沉淀均不溶．根据上述实验信息，请回答下列问题：（1）能确定溶液是（写出溶液标号与相应溶质的化学式）：______（2）不能确定的溶液，写出其标号、溶质可能的化学式及进一步鉴别的方法：______．
