1、初三化學(xué)總復(fù)習(xí)實驗題專項訓(xùn)練1、下圖是實驗室常用的實驗裝置：據(jù)此回答下列問題：（1）寫出a儀器的名稱,B套發(fā)生裝置的名稱：，使用B發(fā)生裝置的優(yōu)點是。（2）①若實驗室用B裝置制取二氧化碳氣體，則制取氣體的原料可選用。A.稀硫酸和塊狀大理石B.濃鹽酸和塊狀大理石C.稀鹽酸和粉末狀大理石D.稀鹽酸和塊狀大理石②實驗室制取二氧化碳的化學(xué)方程式是：。③實驗室要配制一定質(zhì)量的稀鹽酸制取二氧化碳，現(xiàn)有一瓶濃鹽酸，標簽如右圖所示。欲將該瓶濃鹽酸完全稀釋成10%的稀鹽酸，需要加水的質(zhì)量是克。（3）若用F裝置收集二氧化碳，則氣體應(yīng)從端（填m或n）進入；若將收集到的二氧化碳
2、氣體沿?zé)诘谷隓(蠟燭已點燃)中，出現(xiàn)的現(xiàn)象是，該實驗說明二氧化碳具有的性質(zhì)。（4）實驗室用裝置A、C均能制取氧氣，這兩種方法中，最能體現(xiàn)“節(jié)能環(huán)?！崩砟畹氖牵ㄓ没瘜W(xué)方程式）：，該反應(yīng)中二氧化錳的作用是；實驗室用裝置E收集的氧氣不純，可能產(chǎn)生的原因是。2．在化學(xué)實驗中常用石蕊試紙檢驗物質(zhì)的酸堿性：酸性物質(zhì)使藍色石蕊試紙變紅，堿性物質(zhì)使紅色石蕊試紙變藍。某實驗探究小組為了探究碳酸具有酸性而二氧化碳不具有酸性，按下圖進行實驗：請回答：personalandcollectivelearningonyourown,combininglearningreadi
