    Mrs. White lived in a town of England. Her husband died three years ago and one of her children worked

in the capital and the other three lived in another town. Her husband didn't leave her much money and she

had to live a simple life. Sometimes her children went to see her during their holidays, but they stayed with

her for only two or three days.

    One winter morning the old woman got up early. She was going to buy some food in a shop. And when

she came out, she found there was much snow in the street. She had to sweep it away. And suddenly she

found a dying dog at the corner of the house. She picked it up and took it into the house quickly. She put it

near the fire and gave it some milk and bread. At first the poor dog ate nothing and that afternoon it drank

some milk and three days later it was all right. Now the old woman found it was a beautiful dog. And she

liked it very much and took it. everywhere she went. A week later she went shopping with her dog. At a bus

stop a young man was eating fish and chips. The little dog became very excited at the smell of the man's

lunch and began jumping up at him.

    "Do you mind if I throw it a bit?" asked the young man.

    "Not at all," answered Mrs. White.

    Having heard this, he picked up the dog and threw it over the wall.

（13分）工业上生产高氯酸时，还同时生产了一种常见的重要含氯消毒剂和漂白剂

亚氯酸钠（NaClO₂），其工艺流程如下：

已知：

1．NaHSO₄溶解度随温度的升高而增大，适当条件下可结晶析出。

2．高氯酸是至今为止人们已知酸中的最强酸，沸点90℃。
