I still remember my middle school life in that small town. I am then in a school for students from Tibet. As we all left home at a early age, we met lots of problems in our daily life. We had to do the washing, cleaning and shopping by us. However, we seldom felt lonely or helplessly. We enjoyed our happy life. At weekends, we would play basketball, swam in the pool or go for a picnic. We are lived in a big family. We treated each other brothers and sisters. If any one of us had any difficulty with his studies, the other student would help him out. It has been five years when we graduated, but those memories are as sweet as never before.

二氧化铈(CeO2)是一种重要的稀土氧化物。平板电视显示屏生产过程中产生大量的废玻璃粉末(含SiO2、Fe2O3、CeO2等物质)。某课题以此粉末为原料,资源回收的工艺流程如下:

(1)写出第①步反应的离子方程式                                   

(2)洗涤滤渣B的目的是为了除去____(填离子符号),检验该离子是否洗净的方法是            

(3)写出第③步反应的化学方程式_____________________________。

(4)制备绿矾(FeSO4·7H2O)时,向Fe2(SO4)3溶液中加入过量铁屑,充分反应后,经过滤得到FeSO4溶液,再经               、过滤、洗涤、干燥等操作步骤得到绿矾。

(5)取上述流程中得到的Ce(OH)4产品(质量分数为97%)1.0g,加硫酸溶解后,用0.1000mol/LFeSO4溶液滴定至终点(铈被还原成Ce3+),则需准确滴加标准溶液的体积为       mL。
