醫(yī)藥企業(yè)化驗員崗前培訓試題

姓名分數(shù)

一、填空：（共70分）

1.酸式滴定管的試漏：用充滿滴定管，安置在滴定管架上直立靜止分鐘，觀察有無水滴漏下。然后，將活塞旋轉，再在滴定管架上直立靜止分鐘，觀察有無漏下。如果漏水，則應重新進行涂油操作。

2.劇毒品領取必須由領取、發(fā)放，其發(fā)放要本著先入先出的原則，稱量要進行，并填寫領用記錄，注明、、用途。稱量時要戴口罩、手套等。3.無論使用酸式管還是堿式管，都必須掌握三種滴定的方法：（1）的方法，即一般的滴定速度“見滴成線”地方法；（2）控制加入的方法，要做到須加一滴就只能加一滴的熟練操作；（3）學會使液滴，只加半滴，甚至不到半滴的方法。4.容量瓶使用前必須檢查：（1）瓶塞是否；（2）標度刻線位置距離是否太近。如或標線離太近，則不能使用。

5.檢查瓶塞是否漏水的方法如下：加自來水至附近，蓋好瓶塞后，用按住瓶塞，其余手指拿住瓶頸標線以上部分，右手指尖托住平底邊緣，將瓶倒立分鐘，如不漏水，將瓶直立，轉動瓶塞后，再倒立分鐘檢查，如不漏水，方可使用。

6.熔點系指一種物質按照規(guī)定的方法測定時的溫度，是物質的一項，

依法測定熔點，可以鑒別或檢查藥品的。熔點測定用溫度計應為具有℃刻度的

型溫度計，溫度計除應符合的規(guī)定外，還應經常采用進行校正，該物質由分發(fā)，用前應。

7.配制PH測定用標準緩沖液與供試液用水，應是，標準緩沖液最好新鮮配制，如發(fā)現(xiàn)現(xiàn)象，不能繼續(xù)使用。PH值測定過程中，如用標準緩沖液校準時用定位鈕不能調節(jié)至規(guī)定值，應考慮。

8.滴定液的濃度應取位有效數(shù)字表示，滴定管在后并附有使用。9.氫氧化鈉滴定液易，因此在藥典附錄中氫氧化鈉滴定液應貯存于中。

10.代硫酸鈉滴定液配制中應加入作為穩(wěn)定劑，使溶液的PH值保持在，以防止硫代硫酸鈉的分解。配制后應在避光處貯放，待濃度穩(wěn)定，再經濾過，而后標定。11.“精密稱定”0.5g樣品，實際可稱取范圍為�！胺Q定”0.5g樣品，實際可稱取范圍為。取用量為“約0.5g”時，實際可取用范圍為。

12.制藥用水總機碳測定法用于檢查水中有機碳的總量，用于控制水中的含量。測定用儀器應年校定一次。

13.紫外分光光度計用檢定儀器的吸光度的準確度。取在120℃干燥至恒重的重鉻酸鉀mg，精密稱定，加0.005mol/L硫酸溶液溶解并稀釋至1000ml。在規(guī)定波長處測定并計算其吸收系數(shù)，應符合規(guī)定。

14.如規(guī)定量取5ml、5.0ml或5.00ml時，則應分別選用進行量取。

15.碘量法分為法和法。間接碘量法在滴定時應在中進行。碘量法常用的指示劑是。

16.沉淀滴定法中生成難溶性銀鹽的沉淀滴定法是。17.在非水溶液滴定中，除了用指示劑指示終點外，法是指示終點的基本方法。因為在非水溶液滴

定中，有許多物質的滴定，目前還沒有合適的指示劑，而且在選擇指示劑和測定指示劑終點顏色時法是一種非常重要的參考依據(jù)。

18.常用的酸堿指示劑酚酞它的酸式色是色的，堿式色是色的。

19.超凈工作臺使用前要用消毒液后，將物品放置在操作臺面上，打開超凈工作臺電源，紫外燈照射分鐘后關閉。操作時要先打開，，分鐘后，才開始操作；操作完畢后，移出，關閉；接著用擦拭超凈工作臺，關閉日光燈電源。二、選擇題：（10分）

1.洗滌硝酸銀黑褐色殘留污物應選用洗液。

A:堿性高錳酸鉀洗液B、堿性乙醇洗液C、碘－碘化鉀洗液2.下列屬于沉淀滴定法的是。

A.碘量法B.高錳酸鉀法C.鉻酸鉀法D.吸附指示劑法3.下列屬于氧化還原滴定法的是。

A.碘量法B.高錳酸鉀法C.重鉻酸鉀法D.吸附指示劑法4.滴定液的使用期限為2個月的是。

A鹽酸滴定液B氫氧化鈉滴定液C碘滴定液D硫代硫酸鈉滴定液5.按四舍六入五成雙原則,將修約為三位有效數(shù)字得2.32。A.2.3260B.2.3250C.2.3149D.2.3251三、名詞解釋（101、恒重：

2、滴定液的“F”值：

四、計算題：（10分）

.洗滌一只25ml的容量瓶，用自來水洗凈后再用純化水沖洗干凈。假定容量瓶中的殘留水為1ml、自來水中溶解物總量為1000mg/L，用40ml純化水沖洗。如采用每次使用20ml洗滌兩次和每次使用10ml洗滌4次，請以計算證明：玻璃儀器洗滌的原則是少量多次。
