12.高压氧还原法可直接从溶液中提取金属粉。以硫化铜精矿(含Zn、Fe元素的杂质)为上嬖原料制备Cu
粉的匚名流程如卜,可能用到的数据见卜表。
下列说法错误的是
A.固体X主:要成分是Fe(OH)3和S:金限M为Zn
B.没取时,增大。2压强可促进金属离子浸出
C.中和调pH的范困为3.27.2
D.还原时,增大溶液酸度有利于Cu的生成
【答案】D
【解析】
【分析】CuS精矿(含有杂质Zn、Fe元素)在高压O?作用卜\用硫酸溶液浸取,CuS反应产生为CuSO,、S、
HOF6被狗化为Fd.然后加入NH3调节溶液pH,使Fe3♦形成F«OH)3沉淀,而Cu"、Zn"仍以离子
形式存在」溶液中,过滤得到的灌渣中含有S、Fe(OH)3;滤液中含有Cu<Zn>;然后向滤液中通入高压
氏.根据元素活动性:Zn>H>Cu,C1-被还原为Cu单质,通过过滤分肉出来;而Zn>仍然以离手形式
存在丁溶液中.再经系列处理可得到Zn单质。
【详解】A.经过上述分析可知固体X主要成分是S、Fe(OH)3.金属M为Zn.A正确:
B.CuS难溶于硫酸,在溶液中存在沉淀溶解平衡CuS(s)Cu-Xaq)^S-(aq).增大O;的浓度,可以反应
消耗S%使之转化为S,从而使沉淀溶解平衡正向移动,从而可促进金属离子的浸取,B正确:
C.根据流程图可知:用NH;调节溶液pH时,嘤使F/,转化为沉淀,而Cu〉、Zn,仍以离子形式存在于
溶液中,结合离子沉淀的pH范用,可知中和时应该调节溶液pH范阳为3.2〜4.2,C正确:
D.在用H:还原Cu»变为Cu服质时.氐失去电子被辄化为HJ与溶液中0H•结合形成HQ,若还原时
增大溶液的酸度,c(H・)增大,不利于HN失去电户还原Cu单质,因此不利于Cu的生成,D错误:
故合理选项是D.
13.设计如图装置回收金属钻。保持细菌所在环境pH稳定,借助其降解乙酸盐生成CO-将废IH锂离子
电池的正极材料LiCoO;(s)转化为cd,工作时保持厌辄环境,并定时将乙室溶液转移至甲室.已知电
溶液溶液.溶液
A.装置工作时,甲室溶液pH逐渐增大
B.装置工作一段时间后,乙室应补充盐酸
C.乙室电极反应式为LiCoO,+2H,O+e=Lr+C。>+4OH
D.若甲室Co>减少200mg,乙室Co?•增加300mg,则此时己进行过溶液转移
【:父】BD
【解析】
【分析】由于乙室中两个电极的电势差比甲室大,所以乙室是原电池.甲室是电解池,然后根据原电池、
电解池反应原理分析解答。
【详解】A.电池工作时,甲室中细菌上乙酸盐的阴离「失去电广被氧化为CO?气体,C寸在另个电极
上得到电广,被还原产生C。单版,CMCOO•失去电广后,Na♦通过阳膜进入阴极室,溶液变为NaCl溶液.
溶液由碱性变为中性,溶液pH减小,A错误,
B.对于乙室,正极上LiCoO?得到电子,被还原为Co2+.同时得到LiJ其中的O与溶液中的H•结合H:O.
因此电池工作•段时间后应该补充盐酸,B正确:
C.电解质溶液为酸性,不可能大堂存在OH、乙室电极反应式为:LiCcQ+e+dH-Lr+CQ+ZHiO,C错
误,
02e
D.若甲室0=+减少200mu,电子转移物质的最为n(e*)=^7,x2=0.0068mol,乙室Co〉增加300me.

c(SO;)c(SO:)c(Sr")K£S»SO,)
K-c(COt)-cCCOjXSr2*)-K£StCOJ故A正确:
B.由分析可知,曲线①代代含酸酸锚固体的O.lmolL硫酸钠溶液的变化曲线,则瓶酸锂的溶度积
K"SrSO0=10-ssx0.1=lL,,温度不变,溶度积不变,则溶液pH为7.7时•甥离子的浓度为I10"=]—,,
lmol/L
则a为6.5:
C.由分析可知,曲线工衣小含碳酸锂固体的ImoJL碳酸钠溶液的变化曲线,故C正确;
D.由分析可知,瓶酸是强酸,溶液pH变化,溶液中硫酸根离了浓度几乎不变,则含硫酸锂固体的硫酸
钠溶液中锂肉子的浓度几乎不变,所以硫酸锯的生成与溶液pH无关,故D借误;
故选D.
15.Cu.Se是一种钠离子电池正极材料.充放电过程中正极材料立方晶胞(示意图)的组成变化如图所示,
晶胞内未标出因放电产生的0价Cu原子.卜列说法正确的是
Cu2TseNa^Ciij^SeNaCuScNa,Sc
OSe2-ONa\Cu-、CWM能占据的位置•Na-
A.每个C%,Se品胞中c『♦个数为x
B.每个Na:Se晶胞完全转化为Cu“Se晶胞,转移电尸数为8
C.每个NaCuSe品胞中0价CuC广个数为l・x
D.当NayC\*Se转化为NaCuSe时,每转移(l・y)mol电R产生(l・x)molCu原子
【答案】D
【解析】
【详解】A.由晶胞结构可知,位f,顶点和面心的硒离广个数为8xg+6x:=4,位「体内的铜岗广和亚铜
82
国广的个数之和为8,设晶胞中的铜离子和亚铜离干的个数分别为a和b,则a+b=8<x,由化合价代数和
为0可得2a+b=4x2,解得a=4x,故A错误;
B.山题意可知,Na,Sc转化为CuxSc的电极反应式为Na)SoeT(2-x)Cur?uxSe+NaJ由晶胞结构可知,
位于顶点和面心的硒离子个数为8,L+6X;=4,则每个晶胞中含行4个Nafe,转移电子数为%故B错
82
误:
C.由题意可知,CjxSc转化为NaCuSc的电极反应式为CuASe+e-+NT=NaCuSe+(l-x)Cu,由晶胞结构可
知,位于顶点和面心的硒离广个数为8x1十6x:-4.则每个品胞中含有4个NaCuSc,品胞中0价铜而个
82
数为(4Tx),故C错误;
D.由题意可知,NayCuj,xSc转化为NaCuSe的电极反应式为NayCuxSe+(l-y)(r+Na-NaCuSe+(l-x)Cu,
所以每转移(l・y)电子,产生(l-x)mol铜.故D正确:
故选D.
三、非选择题:木题共5小题,共60分。
16.研究笼形包合物结构和性侦具有质要意义。化学式为Ni(CN)x・Zn(NH3)yNC6H6的笼形包介物四方
晶胞结构如图所示(H原子未画出),每个茶环只行N属F该晶胞。品胞参数为a=bwc.a=p=y=90。。

(2)品胞中N原子均参与形成f位键,N产与Zn?♦的配位数之比为:x:y:z=______.:品胞中
《id轨道参与杂化的金属离手是,
(3)毗:喻J[尚代率也可形成类似的笼形包合物.已知毗喔中含有与不类似的W人苑读、则哦咤
中N原子的价层孤电子对占据(埴标号).
