参考答案: 1 AC 2 C 3 C 4 D 5 D 6 A 7 C 8 D 9 D 10 A

11.【解析】由“通入氯水中,得无色透明液”知,溶液中含有 SO2,不含 H2S 和 HBr,再由“向 另一份中加入 HNO3 酸化的 AgNO3 溶液有白色沉淀产生”不能确定是否含有 HCl,因是 原氯水溶液中已经含有 Cl ,CO2 也不能确定是否含有,故 D 项正确。 【答案】D 12.【解析】A 项中溶液滴加酚酞试液变红,则依据指示剂的现象知:该试液一定呈现碱性,
? 该项正确;B 项溶液中可能含有 HCO3 干扰;C 项能使品红溶液褪色的含有 Cl2 等;D


项中此液体可能为强含氧酸如 H2SO4 溶液等或强碱如 NaOH 溶液等或强含氧酸强碱盐如 Na2SO4 等,一定不是纯水,因纯水的导电性太弱。 【答案】A 13.【解析】①中 Cl2 可与乙烷发生取代反应;②中饱和碳酸氢钠溶液可降低乙酸乙酯的溶解 度,便于乙酸乙酯的分层,同时吸收了乙酸,然后分液分离;③中 CO2 气体可与饱和碳 酸钠溶液反应生成碳酸氢钠;④中乙酸与生石灰反应生成沸点高的乙酸钙,由于乙醇具 有挥发性,可用蒸馏法将乙醇蒸馏出。故正确的选项为 B 项。 【答案】B

14.【解析】(1)中有两次白色沉淀的是 Al(NO3)3,两次红褐色沉淀一次气体的是 FeCl3, 四次沉淀的是 NaOH,两次沉淀且沉淀由白色立即变灰绿色最后变红褐色的是 FeSO4, 三次沉淀一次气体的是 NaHCO3,故可实现鉴别;(2)中的 Na2CO3 和 Na2SO4 两两混 合反应,均有两次沉淀不易鉴别出;(3)两两混合反应,KOH 和 NaHCO3 均只有一次 沉淀,NaCl 和 KNO3 均无沉淀,这两组不易鉴别出;(4)(5)(6)均可鉴别出,故 C 项正确。 【答案】C 15.【答案】 (1)NO2 (2)比较碳酸、醋酸、硅酸的酸性强弱 管中产生白色沉淀 16.【答案】 (Ⅰ) (1)关闭弹簧夹(或止水夹)a,由长颈漏斗向锥形瓶内加水至漏斗内液 面高于锥形瓶内液面,静置一会观察液面是否变化,若不变,说明气密性良好,否则、 说明装置漏气
