（15分）重铬酸钠（Na2Cr2O7）主要用于印染、制革、医药、电镀等。工业上以铬铁矿（主要成分FeO·Cr2O3）、碳酸钠、氧气和硫酸为原料生产重铬酸钠（Na2Cr2O7·2H2O）的主要反应如下：

①4FeO·Cr2O3+8Na2CO3+7O28Na2CrO4+2Fe2O3+8CO2

②2Na2Cr04+H2S04．-----~Na2S04+Na2Cr207+H20

（1）反应①是在回转窑中进行，反应时需不断搅拌，

其目的是           。

（2）右图是红矾钠（Na2Cr2O7·2H2O）和Na2SO4的溶

解度曲线。从Na2Cr2O7和Na2SO4的混合溶液中提取Na2Cr2O7，

晶体的操作：先将混合溶液蒸发浓缩，趁热过滤。趁热过滤的目的是          ；然后将滤液       ，从而析出红矾钠。

（3）Na2Cr2O7与KCl或K2SO4进行复分解反应可制取K2Cr2O7，现

用Na2Cr2O7与KCl来制备K2Cr2O7，简述操作步骤（有关物质的溶

解度见右表）：          。

（4）重铬酸钾可用于铁矿石中铁的含量测定，实验步骤如下：

步骤1：将mg铁矿石加浓盐酸加热溶解

步骤2：加入SnCl2溶液将Fe3+还原至黄色消失

步骤3：将所得溶液冷却，加入HgC2溶液，将过量的Sn2+氧化

为Sn4+

步骤4：加人15mL硫酸和磷酸的混合酸及5滴O．2％二苯胺磺酸钠指示剂

步骤5：立即用cmol·L。重铬酸钾溶液滴定至溶液呈稳定紫色，即为终点，消耗重铬酸钾溶液VmL

①写出SnCl2还原Fe3+的离子方程式           。

②如省去步骤③，则所测定的铁的含量         （填“偏高”、“偏低”或“无影响”）。

③步骤5使用的玻璃仪器有
