10、可利用其可燃性采取点燃法来进行尾气处理。 （3）利用黑色固体可溶于盐酸并产生气体，结合“原子守恒”可知用酒精喷灯的乙组实验得到的固体为 Fe；利用甲组现象可知 Fe2O3与 CO在酒精灯加热的条件下，Fe 2O3被还原得到黑色固体为 Fe3O4，由此可写出反应的离子方程式；因 Fe3+遇 SCN-显红色，所以步骤 4中溶液变红是溶液中 Fe2+被 Cl2氧化为 Fe3+所致、溶液褪色的原因可能是 Cl2将 SCN-氧化，若该假设成立，则溶液中还存在 Fe3+，再继续加入 KSCN溶液则溶液变红；若 B处停止加热后，C 中液体易倒吸入 B中引起玻璃管炸裂，因此可采取的改进措施是在装置 B C之间
