1.实驗目的使学生認識一氧化碳中毒的基本道理。在闡明一氧化碳与血紅蛋白的关系。从而达到重視冬季取暖用煤火爐的問题。 2.实驗过程 (1) 課前取1毫升甲酸与4毫升浓硫酸加热产生一氧化碳用吉普发生器收集貯气(或用空瓶排水法收集貯气);(2) 取二个小試管各盛3.5毫升鷄血(加入7％檸檬酸鈉溶液0.5毫生防止血凝固)。教学中讓学生仔細观察二个試管內的鷄血顏色并无差
1. The purpose of the experiment to enable students to understand the basic principles of carbon monoxide poisoning. Explain the relationship between carbon monoxide and hemoglobin. So as to achieve the importance of winter coal stove with heating problems. 2. Experimental Procedure (1) Take 1 ml of formic acid and 4 ml of concentrated sulfuric acid before heating to generate carbon monoxide. Collect the gas by the jeep generator (or collect the gas by the empty bottle draining method); (2) Take two small test tubes 3.5 ml chicken blood (0.5% added 7% sodium citrate solution to prevent blood coagulation). Teaching students to carefully observe the two test tubes of chicken blood color and no difference
