下列关于酒剂与酊剂质量控制的叙述，正确的是（）

A.酒剂不要求乙醇含量测定

B.酒剂的浓度要求每100ml相当于原药材20g

C.酒剂在贮存期间出现少量沉淀可以滤除，酊剂不可以滤除

D.酒剂、酊剂无需进行微生物限度检查

E.含剧毒药的酊剂浓度要求每100ml相当于原药材10g

答案

参考答案：E

解析：本题考查酒剂与酊剂质量的区别。酒剂与酊剂都要求乙醇含量测定、微生物限度检查等内容；酊剂有浓度的要求；含剧毒药的酊剂浓度要求每100ml相当于原药材10g，普通药材的酊剂每100ml相当于原药材20g；酊剂在贮存期间如产生沉淀，可先进行乙醇浓度的调整，若仍有沉淀，可将沉淀滤除，再测定有效成分的含量。

填空题

(14分)

Ⅰ．（1）分析下表中各项的排布规律，按此规律排布第22项应为                  。

12345678910
C2H4C2H6C2H6OC2H4O2C3H6C3H8C3H8OC3H6O2C4H8C4H10
（2）下列反应中属于取代反应的是               。（填序号）

①乙烯使酸性高锰酸钾溶液褪色   ②甲烷和氯气混合光照   ③苯使溴水层褪色

④乙酸和乙醇反应   ⑤乙醇变成乙醛   ⑥葡萄糖发生银镜反应

Ⅱ．A、B、C、D、E、F为原子序数依次增大的六种短周期元素。常温下，六种元素的常见单质中三种为气体，三种为固体。A与E，D与F分别同主族，A能与B、C、D分别形成电子数相等的三种分子，C、D的最外层电子数之和与E的核外电子总数相等。试回答下列问题：

（1）写出下列元素的元素符号： C               ，F                。

（2）分子式为A2B2D4的化合物与含等物质的量的KOH的溶液反应后所得溶液呈酸性，其原因是              。（用方程式及必要的文字说明）。该溶液中各离子浓度由大到小的顺序为                                 。

（3）由A、C、D、F和Fe五种元素可组成类似明矾的化合物Z（相对分子质量为392），1molZ中含有6mol结晶水。对化合物Z进行如下实验：

a．取Z的溶液，加入过量的NaOH浓溶液并加热，产生白色沉淀和无色有刺激性气味的气体。白色沉淀迅速变为灰绿色，最终变为红褐色；

b．另取Z的溶液，加入过量的BaCl2溶液产生白色沉淀，加盐酸沉淀不溶解。

①Z的化学式为                    。

②已知100mL1mol/LZ溶液能与20mL1mol/LKMnO4溶液（硫酸酸化）恰好反应，写出该反应的离子方程式                                                。
