(4)用标准卷尺量取镁带(2分) 12Va/5mx(2分)
20.(10分)
(1)Fe3O4也能被磁铁吸附,故不能由此确定X就是铁单质。(2分)
(2) ①检验是否存在Fe3+,确认Fe3O4的存在(2分) ②Fe+2 Fe3+=3Fe2+ (2分)
(3) ①过滤、洗涤(2分) ②n(Fe3O4)=0.01mol;n(Fe)=0.01mol(2分)
21、(11分)
(1)他们类比的物质是Na2SO4,而Na2SO4具有以下化学性质:与BaCl2溶液反应生成沉淀;Na2SO4溶液呈中性,且不与酸反应;Na2SO4无还原性,不能被氧化剂氧化,因此他们提出以上猜想。(2分)
(2)
实验操作
实验现象或
预期实验现象
现象解释
(用离子方程式表示)
结论
猜想②
操作一:用玻璃棒蘸取Na2S2O3溶液,点滴到pH试纸的中央,将试纸呈现的颜色与标准比色卡对照
操作二:用滴管取少量Na2S2O3溶液于试管,然后逐滴滴入3 mol?L-1H2SO4,振荡
有淡黄色沉淀和无色刺激性气味气体产生
猜想③
操作三:用滴管取少量新制氯水于试管,然后逐滴滴加少量Na2S2O3溶液,振荡
氯水颜色变浅
S2O32―+4Cl2+ 5H2O=2SO42―+8Cl―+10H+
(操作1分,现象1分,离子方程式2分,共7分)
(3)用滴管取少量反应后的溶液于试管,向其中滴入氯化钡溶液,若观察到有白色沉淀产生,则说明Na2S2O3能被氯水氧化(2分)
