2010年安徽省初中毕业学业考试英语试卷
27.(2007年南师大第二附属高级中学高三典型题训练)在氮的化合物中,有一类盐叫亚硝酸盐.如亚硝酸钠(NaNO2)等.它们广泛用于印染、漂白等行业,在建筑行业用作防冻剂,在食品工业作防腐剂和增色剂;它是一种潜在致癌物质,过量或长期食用对人产生危害,由于亚硝酸钠有咸味,外观与NaCl相似,曾多次发生过被误当食盐食用的事件。
某同学查阅有关资料,了解到以下相关信息:

试回答下列问题:
(1)人体正常的血红蛋白中应含Fe2+.若误食亚硝酸盐(如NaNO2),则导致血红蛋白中Fe2+转化为Fe3+而中毒,服用维生素C可解毒.下列叙述不正确的是________.
A.亚硝酸盐是还原剂 B.维生素C是还原剂
C.维生素C将Fe3+还原为Fe2+ D.亚硝酸盐被还原
(2)下列方法中,不能用来区别NaNO2和NaCl的是________.
A.测定这两种溶液的pH B.用AgNO3和HNO3两种试剂来区别
C.在酸性条件下加入KI淀粉试液来区别 D.分别在这两种溶液中滴加甲基橙
(3)一般的自来水中含多种离子,如Na+、Ca2+、Cl-、SO42-、NO3-等,专家提出不能喝“千滚水”(指多次煮沸的水),请你用化学知识解释其合理性 ______________________________________。
(4)为了测定某样品中NaNO3的含量,可以使用标准KMnO4溶液进行滴定,试回答:
①KMnO4溶液在滴定过程中作________(填“氧化剂” “还原剂”),该滴定过程________(填“要”或“不要”)另加指示剂.
②若滴定终点读数时目光俯视,则所得结果________(填“偏大”“偏小”“无影响”).
(5)某同学在家中欲进行鉴别NaCl与NaNO2的实验,但他家中只有浓醋酸,请问该实验能否成功?说明理由。
(6)现有氮的三种常见氧化物组成的混和气体44.8L(体积已换算成标准状态),其中N2O4、NO体积分数都为20%。
①将该气体通入适量的NaOH溶液中恰好反应,则溶液中NaNO2的质量是 g;
②反应后的溶液蒸干灼烧则NaNO2物质的量 mol。
答案 (1)A (2)D (3)NO2-+Cl2+H2O=NO3-+2H++2Cl- (4) ①氧化剂, 不要 ②偏小
(5)能,强酸制取弱酸,生成的HNO2分解为红棕色NO2气体。 (6)110.4 2.4
26.2007年普陀区高三质量调研)在120mL 12.5mol/L的硝酸中,加入m克的Fe后,在加热条件下恰好完全反应,收集到NO与NO2的混合气体,将气体通过低温使NO2完全转化为N2O4晶体,得到11.5克晶体,反应后在溶液中滴入KSCN溶液,发现溶液不显红色。
(1)加入Fe的物质的量为 ;
(2)反应中收集到的气体中NO的体积为 (标准状态下);
答案(1)0.5 mol (2)5.6 L
