姓名分数
一、填空：（共70分）
1.酸式滴定管的试漏：用充满滴定管，安置在滴定管架上直立静止分钟，观察有无水滴漏下。然后，将活塞旋转，再在滴定管架上直立静止分钟，观察有无漏下。如果漏水，则应重新进行涂油操作。
2.剧毒品领取必须由领取、发放，其发放要本着先入先出的原则，称量要进行，并填写领用记录，注明、、用途。称量时要戴口罩、手套等。3.无论使用酸式管还是碱式管，都必须掌握三种滴定的方法：（1）的方法，即一般的滴定速度“见滴成线”地方法；（2）控制加入的方法，要做到须加一滴就只能加一滴的熟练操作；（3）学会使液滴，只加半滴，甚至不到半滴的方法。4.容量瓶使用前必须检查：（1）瓶塞是否；（2）标度刻线位置距离是否太近。如或标线离太近，则不能使用。
5.检查瓶塞是否漏水的方法如下：加自来水至附近，盖好瓶塞后，用按住瓶塞，其余手指拿住瓶颈标线以上部分，右手指尖托住平底边缘，将瓶倒立分钟，如不漏水，将瓶直立，转动瓶塞后，再倒立分钟检查，如不漏水，方可使用。
6.熔点系指一种物质按照规定的方法测定时的温度，是物质的一项，
依法测定熔点，可以鉴别或检查药品的。熔点测定用温度计应为具有℃刻度的
型温度计，温度计除应符合的规定外，还应经常采用进行校正，该物质由分发，用前应。
7.配制PH测定用标准缓冲液与供试液用水，应是，标准缓冲液最好新鲜配制，如发现现象，不能继续使用。PH值测定过程中，如用标准缓冲液校准时用定位钮不能调节至规定值，应考虑。
8.滴定液的浓度应取位有效数字表示，滴定管在后并附有使用。9.氢氧化钠滴定液易，因此在药典附录中氢氧化钠滴定液应贮存于中。
10.代硫酸钠滴定液配制中应加入作为稳定剂，使溶液的PH值保持在，以防止硫代硫酸钠的分解。配制后应在避光处贮放，待浓度稳定，再经滤过，而后标定。11.“精密称定”0.5g样品，实际可称取范围为。“称定”0.5g样品，实际可称取范围为。取用量为“约0.5g”时，实际可取用范围为。
12.制药用水总机碳测定法用于检查水中有机碳的总量，用于控制水中的含量。测定用仪器应年校定一次。
13.紫外分光光度计用检定仪器的吸光度的准确度。取在120℃干燥至恒重的重铬酸钾mg，精密称定，加0.005mol/L硫酸溶液溶解并稀释至1000ml。在规定波长处测定并计算其吸收系数，应符合规定。
14.如规定量取5ml、5.0ml或5.00ml时，则应分别选用进行量取。
15.碘量法分为法和法。间接碘量法在滴定时应在中进行。碘量法常用的指示剂是。
16.沉淀滴定法中生成难溶性银盐的沉淀滴定法是。17.在非水溶液滴定中，除了用指示剂指示终点外，法是指示终点的基本方法。因为在非水溶液滴
定中，有许多物质的滴定，目前还没有合适的指示剂，而且在选择指示剂和测定指示剂终点颜色时法是一种非常重要的参考依据。
18.常用的酸碱指示剂酚酞它的酸式色是色的，碱式色是色的。
19.超净工作台使用前要用消毒液后，将物品放置在操作台面上，打开超净工作台电源，紫外灯照射分钟后关闭。操作时要先打开，，分钟后，才开始操作；操作完毕后，移出，关闭；接着用擦拭超净工作台，关闭日光灯电源。二、选择题：（10分）

A盐酸滴定液B氢氧化钠滴定液C碘滴定液D硫代硫酸钠滴定液5.按四舍六入五成双原则,将修约为三位有效数字得2.32。A.2.3260B.2.3250C.2.3149D.2.3251三、名词解释（101、恒重：
2、滴定液的“F”值：
四、计算题：（10分）
.洗涤一只25ml的容量瓶，用自来水洗净后再用纯化水冲洗干净。假定容量瓶中的残留水为1ml、自来水中溶解物总量为1000mg/L，用40ml纯化水冲洗。如采用每次使用20ml洗涤两次和每次使用10ml洗涤4次，请以计算证明：玻璃仪器洗涤的原则是少量多次。
