人教版初中九年级化学下册第九单元《溶液》测试题(含答案解析)

一、选择题1.化学概念之间在逻辑上存在并列、交叉和包含等关系。

下列各图中概念之间关系不正确的是( )A.B.C.D. A解析:AA、物质分为混合物和纯净物,混合物是由两种或两种以上的物质组成,因此混合物与纯净物属于并列关系,不是交叉关系,错误符合题意,故选项正确;B、由两种或两种以上的元素组成的纯净物叫化合物。

氧化物是指由两种元素组成的化合物中,其中一种元素是氧元素,因此它们之间属于包含关系,正确但不符合题意,故选项错误;C、化合反应是有两种或两种以上的物质生成一种物质的化学反应,氧化反应是物质与氧发生的化学反应,因此它们是交叉关系,正确但不符合题意,故选项错误;D、溶液分为饱和溶液与不饱和溶液,饱和溶液与不饱和溶液是并列关系,正确但不符合题意,故选项错误;故选:A。

2.常温下,对100mL氯化钠饱和溶液进图示实验。

下列分析错误的是A.实验1后,甲、乙中溶液的溶质质量分数相等B.实验2后,甲中溶液为氯化钠的不饱和溶液C.实验2后,甲、乙中溶液的溶质量分数相等D.实验2后,甲、乙中溶液所含溶质质量相等C解析:CA、溶液具有均一性,故实验1后,甲、乙中溶液的溶质质量分数相等,故A分析正确,不符合题意;B、实验2后,甲中溶液为氯化钠的不饱和溶液正确,因为加入了溶剂,故B分析正确,不符合题意;C、实验2是常温下向氯化钠的饱和溶液中继续加入5g氯化钠,温度不变,溶解度不变,故加入的氯化钠不能溶解,乙中溶液溶质质量分数不变,甲中溶液溶质质量分数变小,故C分析错误,符合题意;D、实验2后,甲、乙中溶液所含溶质质量相等正确,因为甲中加水,溶质不变,乙中的加溶质不再溶解,因此甲、乙中溶液所含溶质质量相等,故D分析正确,不符合题意。

故选C。

3.下列关于水和溶液的说法不正确的是A.蔗糖溶于水可形成溶液B.溶液由溶质和溶剂组成,所以溶液一定是混合物C.将10%的KNO3溶液倒出一半,剩余溶液中溶质的质量分数为5%D.改变条件,能够使饱和溶液与不饱和溶液相互转化C解析:CA、蔗糖溶于水可形成溶液,溶质是蔗糖,溶剂是水,故A说法正确;B、溶液由溶质和溶剂组成,特征是均一稳定的混合物,故B说法正确;C、溶液具有均一性,将10%的KNO3溶液倒出一半,剩余溶液中溶质的质量分数为10%,故C不正确;D、饱和溶液与不饱和溶液可以相互转化,故D说法正确。
