     Such English idioms as "as poor as a church mouse" and "like a drowned (淹死的) rat" remind people of

the unfavorable images (形象) of mice and rats. But with his efforts in the 20th century, an American young

man Walt Disney changed people's view.

     Born in 1901 in Chicago, Walt Disney was a newspaper seller, and was fond of drawing pictures. Later

he went to study arts in a Chicago institute. One day when he was thinking hard how to draw a picture in a

building, several mice crawled (爬) onto the drawing board. Walt fed them with bread bits, and they played

happily.

     Suddenly an idea struck Walt. He drew a mouse on the paper and named it Mickey. Then Walt began to

make cartoon films based on Mickey. He also made use of the newest skill in dubbing (为....配音) in his

cartoons so that Mickey was able to talk. In 1932 a Walt Disney cartoon film won the Oscar.

     In mid-1950s, Walt planned a Disneyland in California, and within 10 years, Mickey, the little mouse,

helped him to make 200 million dollars. Then another Disneyland was set up in Florida, Mickey Mouse seemed

to become the symbol (象征) of American amusements.

     In the Mickey Mouse films, when Mickey did anything wrong or foolish, letters of protest (抗议) would

soon be sent to Disney. He then created Donald Duck and Pluto to do the silly things so that Mickey was

always pretty and honest. With Mickey Mouse, Walt Disney challenged the worldly view that it was able to

change the nature of anything born in dirty surroundings.

（12分）高铁酸钾是一种高效的多功能的水处理剂。工业上常采用NaClO氧化法生产，原理为：

3NaClO + 2Fe(NO3)3 + 10NaOH＝2Na2FeO4↓+ 3NaCl + 6NaNO3 + 5H2O

Na2FeO4＋2KOH＝K2FeO4＋2NaOH

主要的生产流程如下：

（1）写出反应①的离子方程式_____________________________。

（2）流程图中“转化”是在某低温下进行的，说明此温度下Ksp(K2FeO4) _________ Ksp(Na2FeO4)（填“＞”或“＜”或“＝”）。

（3）反应的温度、原料的浓度和配比对高铁酸钾的产率都有影响。

图1为不同的温度下，Fe(NO3)3不同质量浓度对K2FeO4生成率的影响；

图2为一定温度下，Fe(NO3)3质量浓度最佳时，NaClO浓度对K2FeO4生成率的影响。

①工业生产中最佳温度为_______℃，此时Fe(NO3)3与NaClO两种溶液最佳质量浓度之比为_______。

②若NaClO加入过量，氧化过程中会生成Fe(OH)3，写出该反应的离子方程式：

____________________________________________________。

若Fe(NO3)3加入过量，在碱性介质中K2FeO4与Fe3+发生氧化还原反应生成K3FeO4，此反应的离子方程式：____________________________________。

（4）K2FeO4 在水溶液中易水解：4FeO42—+10H2O4Fe(OH)3+8OH—+3O2↑。在“提纯”K2FeO4中采用重结晶、洗涤、低温烘干的方法，则洗涤剂最好选用_______溶液（填序号）。

A．H2O

B．CH3COONa、异丙醇

C．NH4Cl、异丙醇

D．Fe(NO3)3、异丙醇
