第I卷 选择题(共48分)
一、请从每小题四个选项中选出一个最符合题意的选项,每小题3分。
1.化学与生活密切相关,下列说法中正确的是( )
A. 生石灰可用作食品抗氧化剂
B. 熟石灰、铁粉常用于食品干燥剂
C. 维生素C因具有酸性,可作食品抗氧化剂
D. 银器久置后表面变暗,是因为发生了化学反应
【答案】D
【解析】
【详解】A.生石灰具有吸水性,可作食品干燥剂,没有还原性,不能作食品抗氧化剂,A错误;
B.铁粉没有吸收水,不能作干燥剂,它具有还原性,做抗氧化剂,B错误;
C.维生素C可以与氧气反应,消耗了食品袋内的氧气,可作食品抗氧化剂,体现了维生素C的还原性,C错误;
D. 银属于不活泼金属,在空气中性质较稳定,不易与空气中的氧气直接反应,但长期接触空气中的微量H2S气体后,则会与之反应生成黑色硫化银,故导致银器表面变暗,属于化学变化,故D正确;
综上所述,本题选D。
2.下列有关氧化还原反应的叙述中正确的是 ( )
A. 有单质参加或有单质生成的反应一定是氧化还原反应
B. 氧化还原反应的本质是元素化合价的升降
C. 金属单质在化学反应中一定作还原剂
D. 失电子的反应物在反应中作还原剂,反应中被还原
【答案】C
【解析】
【分析】
氧化还原反应的本质是有电子的转移,即氧化还原反应中一定有元素化合价的变化,在氧化还原反应中得电子的反应物作氧化剂,被还原,失电子的反应物作还原剂,被氧化;据以上分析解答。
【详解】A.有单质参加或有单质生成的反应不一定是氧化还原反应,如:石墨转化为石就不是氧化还原反应,故A错误;
B.氧化还原反应的本质是有电子的转移,故B错误;
C.在化学反应中,金属最外层电子很容易失去,所以金属单质常常作还原剂, 故C正确;
