某小组研究SCN﹣分别与Cu2+和Fe3+的反应． 实验中cKSCN＝0.1mol/Lc[Fe2SO43]＝0.025mol/LcCuSO4＝0.05mol/L． Ⅰ．KSCN溶液与CuSO4溶液反应实验如下． 资料ⅰ．Cu2+可与SCN﹣反应生成CuSCN白色沉淀和SCN2． ⅱ．SCN2称为“拟卤素”在水溶液中呈黄色SCN2的化学性质与Cl2相似可与水碱等发生反应． 1a中CuSO4溶液显酸性的原因是用离子方程式表示． 2a→b中试管内溶液pH减小可能的原因是． 3b→c产生沉淀的原因是． Ⅱ．同学们根据相同条件下氧化性Fe3+＞Cu2+预测Fe3+与SCN﹣也可发生类似a中的氧化还原反应进行如下实验． 4向Fe2SO43溶液中滴入少量KSCN溶液观察到表明发生了反应Fe3++3SCN﹣⇌FeSCN3． 5基于4继续实验用Fe2SO43溶液KSCN溶液与石墨电极电压表盐桥等组装成原电池电压表指针几乎不偏转．该实验的目的是． 6查阅资料并讨论后得出溶液中离子在反应时所表现的氧化性强弱与相应还原产物的价态和状态有关．由此分析a中反应发生的原因生成CuSCN沉淀使Cu2+的氧化性增强并补充实验进一步证明．补充的实验是． 7取4中反应后溶液逐滴加入K3[FeCN6]溶液产生蓝色沉淀并且沉淀量逐渐增多．该实验结果与5中实验结果不一致解释原因． 8为进一步证实7中的解释在以上实验的基础上补充实验其操作及现象是．

某小组模拟工业上回收分银渣中的银过程如图1 1Na2SO3溶液和氨水均可作浸出剂但由于氨水易填物理性质故用Na2SO3溶液更环保． 2Ⅰ中主要反应AgCl+2SO32﹣⇌AgSO323﹣+Cl﹣．研究发现其他条件不变时该反应在敞口容器中进行浸出时间过长会使银的浸出率浸出液中银的质量占起始分银渣中银的质量的百分比降低可能原因是用离子方程式表示． 3研究发现浸出液中含银化合物总浓度与含硫化合物总浓度及浸出液pH的关系如图2． ①pH＝10时含银化合物总浓度随含硫化合物总浓度的变化趋势是 ②解释①中变化趋势的原因 ③pH＝5时含银化合物总浓度随含硫化合物总浓度的变化与pH＝10时不同原因是 4将Ⅱ中反应的离子方程式补充完整AgSO323﹣+OH﹣+═+++CO32﹣ 5Ⅲ中回收液可直接循环使用但循环多次后银的浸出率会降低．从回收液离子浓度变化和反应限度的角度分析原因
