    于水得到盐酸,所以液面上方氧气体积分数增加,D正确。飞【会案)B【解析】钙离子用碳酸根离于近淀,线离子用氢氧根离子沉淀,责酸根离子用领离子沉淀,过滤要放在所有的沉淀操作之后,加碳酸钠要放在加氯化钡之后,可以将过量的领离子沉淀,据此分析。镁离子用氢氧根离子沉淀,加入过量的氢氧化钠可以将镁离子沉淀,疏酸根离子用钡离子沉淀,加入过量的氯化钡可以将硫酸根离子沉旋,至于先除镁离子,还是先除硫酸根离子都行,钙离子。用碳酸根离子沉淀,除钙离子加人碳酸钠转化为沉淀,但是加入的碳酸钠要放在加入的氧化钡之后,这样碳酸钠会除去反应利余的氯化钡,离子都沉淀了,再进行过滤,最后再加入盐酸除去反应剩余的氢氧根离子和碳酸根离子,所以正确的顺序为:③加过量的氯化钡溶液,除去硫酸根离子BaCk+NaSO,BaSO,1+2NaCi:②加过量的氢氧化钠溶液,除去MgCb,主要反应3MgCh+2 NaOH-Mg(Om2+2NaC1,④加过量的碳酸钠溶液,除去Ca2和Ba:aCo,+CaCh=Caco,+2NaC,NaC0 BaCk-BaCO,+2NaC:①过滤:再加适量盐酸.除去迁量的NaOH和Na2C0HCH+NaOH-NaC1HO、2HCaC0,2NaC+H20iC021,蒸发溶液,析出aC晶体,答案选D。【点晴】本题的易错点是碳酸钠要放在加入的氯化钡之后,这样碳酸钠会除去反应剩余的氯化钡,需要注意除杂设计时不要入新的杂质,操作简便,例如过滤放在所有离子沉淀完之后。养8【答案】B【解析A.金属钠具有强还原性,与硫酸铜溶液反应时,先与溶液中的水反应,不能置换制取金属铜,故A错误;B.碳酸氢钠和气气反应且碳酸氢钠碱性较弱,氯气制备工厂若发生泄漏时,因此可用NHCO溶液浸湿软布蒙住口鼻,由于氯气密度比空气大,因此往高处撤离,故B正确:OC.02自身并不含有氧分子,过氧化钠能与人呼吸产生的二氧化碳和水分别反应生成氧气,常用作呼吸面具供氧剂,故C错误D纯净的氢气在氯气中燃烧发出苍白色火焰,故D错误。日9.【答案】D,【解析上焰色试验没有新物质生成,是物理变化,A错误:做焰色试验时用盐酸洗涤铂丝,氯化物熔点较低,加热能除掉xB错误:焰色试验不是所有金属的性质,一般只有外层电子数比较少的容易产生焰色,C错误:钠元素的焰色为黄色,透过蓝色钴玻璃观察钾元素焰色试验的颜色为紫色,可排除钠元素黄色火焰的干扰,D正确。10.【答案】D【解析】A,由发生的反应可知反应1原理:CO2+NH+NaC+H20三NaHCO3+NHC故A正确;B碳酸氢钠溶解度较小,但仍有部分可溶解,电离出HCO,故B错误;C向饱和氯化钠溶液中先通入足量的氨气,使溶液皇碱性易吸收更多二氧化碳,故C正确,D、煅烧碳酸氢钠固体不能在蒸发皿中进行,敌正确:答案选B。11.【答案】C【解析】A项,BrC1与Ca(OiH反应的化学方程式为:·2BrCl+2Ca(OH),=CaCh+Ca(B0)2+2H0,产物有CaC2、Ca(BrO)2和H0,错误;B项,BrCl与水反应的化学方程式为:BCI+H0=HC1+HB0,反应中无化合价改变,不是氧化还原反应,水既不是氧化剂也不是还原剂,错误;C项,BC具有较强的氧化性,与Br:相似,可与碘化钾反应生成单质碘,能使湿润的淀粉碘化钾试纸变蓝,正确;D项,由于2Fe十3B2=2FeBr,BrCl能将Fe氧化成Fe3,故BrC1与铁反应公岩的化学方程式为:2FPe+3BCI=EeB十FeC,错误。黑过,类代当甘司家察事园亮12【答案】B【解析】A.盐酸属于混合物,故A错误;B.氢氧化钠、食盐水、氯化铵、二氧化硫分别属于纯净物、混合物、电解质以及非电解质,故B正确:C,铜属于单质,不屑于电解质联酸钙(6页)第2页
