XX series of effective information 九年级化学（上册）知识点大全（基础篇）第一单元走进化学世界一、药品的取用使用化学药品要做到 三不 ：不能用手接触药品；不要把鼻孔凑到容器口去闻药品的气味；不得尝任何药品的味道。实验室用剩的药品做到 三不：不能放回原瓶；不要随意丢弃；更不要

49、拿出实验室。1. 固体药品的取用小颗粒或粉末状药品应用药匙或纸槽。一斜二送三直立 块状或密度大的金属颗粒可用镊子夹取。 一横二放三慢竖 2. 液体药品取用(1) 少量液体可用胶头滴管取用，向指定仪器中滴入时， 应在仪器的正上方垂直滴入。注意：胶头滴管不能倒放、乱放、平放，应放在指定位置不要伸入容器内，一般要做到悬空垂直四不要。（2）从细口瓶倒取试液时，应把瓶塞拿下，倒放在桌上，倒液体时，瓶上的标签应向着手心，以防止瓶口残留的药液流下来腐蚀标签。同时使瓶口紧靠在试管口或仪器口。3. 取用一定量的药品量取一定体积的液体时一般用量筒。使用时，应使量筒放平稳，倒入液体到接近要求的刻度，再用胶头滴管逐滴

50、滴入量筒至刻度线，读数时使视线与量筒内液体的凹液面最低处保持水平。俯视、仰视都会有误差。二、物质的加热1. 热源 - 加热工具：最常用酒精灯，有时需要喷灯进行高温加热。酒精灯火焰分外焰、内焰、焰心三部分，外焰温度最高，焰心温度最低，因此，加热时应把需加热物质放在外焰部分。酒精灯内的酒精不超过其容积的2/3 。2. 可以直接加热的仪器：试管、蒸发皿、坩埚等；3. 可以加热但必须垫上石棉网的仪器：烧杯、烧瓶等；4. 不能加热的仪器：量筒、集气瓶、漏斗等。5. 给试管里药品加热时应先使试管均匀受热，（来回移动酒精灯或移动试管），然后对准药品所在部位加热。给固体加热时，一般试管口应略向下倾斜，给液体加
