高一化学期末复习第一章从实验学化学第一节化学实验基本方法一、熟悉化学实验基本操作危险化学品标志，如酒精、汽油——易然液体；浓H2SO4、NaOH（酸碱）——腐蚀品[练习]1.下列实验操作正确的是（）A.不慎将浓硫酸沾到皮肤上，立即用大量水冲洗。
B.在食盐溶液蒸发结晶的过程中，当蒸发皿中出现较多量固体时即停止加热。
C.先在天平两个托盘上各放一张相同质量的纸，再把氢氧化钠固体放在纸上称量。
D.过滤时，慢慢地将液体直接倒入过滤器中。
二、混合物的分离和提纯：1、分离的方法：①过滤：固体(不溶)和液体的分离。
②蒸发：固体(可溶)和液体分离。
③蒸馏：沸点不同的液体混合物的分离。
④分液：互不相溶的液体混合物。
⑤萃取：利用混合物中一种溶质在互不相溶的溶剂里溶解性的不同，用一种溶剂把溶质从它与另一种溶剂所组成的溶液中提取出来。
[练习]2.请从上面选择下列各混合物的分离方法（填序号）（1）食盐水与泥沙____________（2）海水晒盐__________（3）CCl4和水__________ （4）蒸馏水的制取____________（5）用CCl4将碘水中的碘提取出来__________2、粗盐的提纯：（1）粗盐的成分：主要是NaCl，还含有MgCl2、CaCl2、Na2SO4、泥沙等杂质（2）步骤：①将粗盐溶解后过滤；②在过滤后得到粗盐溶液中加过量试剂BaCl2(除SO42－)、Na2CO3(除Ca2＋、过量的Ba2＋)、NaOH(除Mg2＋)溶液后过滤；③得到滤液加盐酸(除过量的CO32－、OH－)调pH=7得到NaCl溶液；④蒸发、结晶得到精盐。
加试剂顺序关键：（ⅰ）Na2CO3在BaCl2之后；（ⅱ）盐酸放最后。
3、蒸馏装置注意事项：①加热烧瓶要垫上石棉网；②温度计的水银球应位于蒸馏烧瓶的支管口处；③加碎瓷片的目的是防止暴沸；④冷凝水由下口进，上口出。
4、从碘水中提取碘的实验时，选用萃取剂应符合原则：①萃取剂不能与被萃取的物质反应；②萃取剂与原溶液溶剂互不相溶。

高一复习资料大全高一是人生中最重要的一年，也是最忙碌的一年，这一年里我们要学习各种各样的科目，面对各种各样的挑战，更要发现自己的优势和劣势。
为了更好的应对高一这一年，我们需要收集各种有用的资料，以便我们更好的完成学业。
首先，在高中阶段，语文是学生必学的科目之一。
学好语文，对提高整个人的素质熟练掌握语言最为重要。
所以，我们可以以各种语文辅导资料为主线展开复习，比如：现代汉语词典、书籍《辞源》、中小学生必读名著等等。
第二，在数学上，高一的数学复习是非常重要的。
所有的高中数学知识都要从高一开始。
为了成为数学高手，我们可以从基础书籍开始复习，例如：初中课程要点梳理、《高中数学（必修）》、同步习题集（高中数学）等等。
第三，在英语上，学习英语可以拓宽我们的视野。
母语笔译、英语学习、英语口语、英语阅读都要掌握。
我们可以收集与英语相关的优秀资料，例如：英语词典、《小妇人》、《双语阅读》杂志等等。
第四，在物理、化学和生物科学方面，高一的基本课程会涉及这些方面的内容。
我们也可以准备各科教材、习题集、试题库、自我评估等等，辅助学习物理、化学和生物的知识。
第五，在历史学科方面，需要大量地背诵明朝、清朝、民国三时期的历史事件、人物等。
我们可以准备名人传记、史实剪报和学习笔记等等，有了这些资料也能够轻松背诵各个历史内容。
第六，在地理学科方面，只有熟悉了常见地理概念，才能学好地理。
我们也可以准备地图资料、全国城市地理、中国发展史等各种辅助材料，更好地学习地理知识。
总而言之，高一学习难度大、学科繁重、日程安排很紧张。
然而，凭借正确的学习方法和资源的支持，我们可以更好的应对高中生活。
所以，我们需要认真学习每一门课程，收集各种有用的复习资料，提高我们的学习效率，不断进步，最终取得优异的成绩。
