1、免费 2011高考化学知识点整理模板1 高中化学所有知识点整理 一.中学化学实验操作中的七原则 掌握下列七个有关操作顺序的原则，就可以正确解答“实验程序判断题”。 1.“从下往上”原则。以Cl2实验室制法为例，装配发生装置顺序是:放好铁架台?摆好酒精灯?根据酒精灯位置固定好铁圈?石棉网?固定好圆底烧瓶。 2.“从左到右”原则。装配复杂装置应遵循从左到右顺序。如上装置装配顺序为:发生装置?集气瓶?烧杯。 3.先“塞”后“定”原则。带导管的塞子在烧瓶固定前塞好，以免烧瓶固定后因不宜用力而塞不紧或因用力过猛而损坏仪器。 4.“固体先放”原则。上例中，烧瓶内试剂MnO2应在烧瓶固定前装入，以免固体放入
2、时损坏烧瓶。总之固体试剂应在固定前加入相应容器中。 5.“液体后加”原则。液体药品在烧瓶固定后加入。如上例中浓盐酸应在烧瓶固定后在分液漏斗中缓慢加入。 6.先验气密性(装入药口前进行)原则。 7.后点酒精灯(所有装置装完后再点酒精灯)原则。 二.中学化学实验中温度计的使用分哪三种情况以及哪些实验需要温度计 1.测反应混合物的温度:这种类型的实验需要测出反应混合物的准确温度，因此，应将温度计插入混合物中间。 ?测物质溶解度。?实验室制乙烯。 2.测蒸气的温度:这种类型的实验，多用于测量物质的沸点，由于液体在沸腾时，液体和蒸气的温度相同，所以只要测蒸气的温度。?实验室蒸馏石油。?测定乙醇的沸点。
3、3.测水浴温度:这种类型的实验，往往只要使反应物的温度保持相对稳定，所以利用水浴加热，温度计则插入水浴中。?温度对反应速率影响的反应。?苯的硝化反应。 三.常见的需要塞入棉花的实验有哪些 需要塞入少量棉花的实验: 热KMnO4制氧气 制乙炔和收集NH3 engineering construction and acceptance specification for 5 GB50275-98 compressor, fan and pump installation engineering construction and acceptance specification for liftin
