43、硫酸铅不溶于水，因此滤渣1 的主要成分除SiO2 外还有PbSO4；要测定铁离子，需要调节溶液的pH，又因为不能引入新杂质，所以需要利用氧化锌调节pH，即氧化除杂工序中ZnO 的作用是调节溶液的pH。根据表中数据可知沉2+淀亚铁离子的pH较大，所以若不通入氧气，其后果是无法除去杂质Fe。2+2+2+Cd。（3）溶液中的Cd 可用锌粉除去，反应的离子方程式为Zn+Cd Zn（4）电解硫酸锌溶液制备单质锌时，阴极发生得到电子的还原反应，因此阴极是锌离子放电，则阴极的电极反应式为2+2eZn Zn；阳极是氢氧根放电，破坏水的电离平衡，产生氢离子，所以电解后还有硫酸产生，因此沉积锌后的电解液可返回溶浸
