A．較多量液體加熱﹣﹣燒杯                                      

B．少量試劑的反應(yīng)﹣﹣試管                                      

C．吸取和滴加少量液體﹣﹣膠頭滴管                              

D．盛放固體藥品﹣﹣細(xì)口瓶                                      

Answer 1

【考點(diǎn)】常用儀器的名稱和選用．                                 

【專題】常見(jiàn)儀器及化學(xué)實(shí)驗(yàn)基本操作．                           

【分析】A、較多量液體的加熱，用燒杯；                          

B、少量試劑的反應(yīng)容器，用試管；                                

C、吸取和滴加少量液體，用膠頭滴管；                            

D、盛放固體藥品，用廣口瓶．                                    

【解答】解：                                                

A、燒杯用于較多量液體加熱，故A正確；                          

B、試管用于少量試劑的反應(yīng)，故B正確；                          

C、膠頭滴管用于吸取和滴加少量液體，故C正確；                      

D、廣口瓶用于盛放固體藥品，故D錯(cuò)．                            

故選D．                                                    

【點(diǎn)評(píng)】本題主要考查了常用儀器的名稱和選用，比較簡(jiǎn)單，只有掌握儀器的用途，才能安全、準(zhǔn)確地進(jìn)行化學(xué)實(shí)驗(yàn)．
