    淀的转化,B项不符合题意;为了预防龋齿,使用含氟牙膏,发生的反应为C(PO4)3OH(s)+F-(aq)=Ca(PO4)3F(s)十OH-(aq),属于沉淀的转化,C项不符合题意;向亚硫酸钡中加入硝酸,其可转化为硫酸钡,发生的是氧化还原反应,不属于沉淀的转化,D项符合题意。8.C【解题分析】加水时电离衡HAc一H+十Ac正向移动,导致HAc的电离程度一直增大,开始时只有醋酸分子,不导电,加水后HAc不断电离,离子浓度增大,导电能力增强,但随着溶液体积增大,离子浓度减小,导电能力又减弱,A项错误;NH3·H2O和HAc均为弱电解质,故NH和Ac均能发生水解,即NH+H2O=NH3·H2O+H+,Ac+H2O=HAc+OH,常温下测得NH4Ac水溶液的pH=7.O,说明NH4和Ac的水解程度相当,而不是因为二者不发生水解,B项错误;HAc和NaOH恰好完全反应生成NaAc,根据元素质量守恒可知,此时溶液中存在c(Na)=c(Ac)十c(HAc),C项正确;根据Ka(HAc)=c(H):cAc-1.0X1045,常温下pH为4.76时,则有c(Ac)=c(HAc),由于HAcc(HAc)的电离程度大于Ac的水解程度,所以混合前HAc溶液的物质的量浓度比NaAc溶液的小,D项错误。9.B【解题分析】由水电离出的c(H+)=1×10-12ol·L1的溶液,可能呈酸性,也可能呈碱性,HCO5在酸性条件下不能大量存在,HCO3、Mg2+在碱性条件下不能大量存在,A项错误;Kwc(H+)=1×10-13mol·L-1的溶液中,c(H+)=0.1mol·L-1,H+、NH、Ca2+、C1、NO反应,一定能大量共存,B项正确:《1的溶液呈中性,℉e在中性溶液中全沉淀,不能大量存在,C项错误;与A1反应放出H2的溶液可能呈碱性,也可能呈酸性,若溶液呈碱性,OH与Mg2+、Cu+不能大量共存,若溶液呈酸性,AI与H、NO3发生反应不能生成H2,D项错误。10.C【解题分析】原电池工作时,阳离子移向正极,阴离子移向负极,铜锌原电池中,盐桥中的K和NO5分别移向正极和负极,A项错误;合成氨的过程中,将NH3液化分离,不能加快正反应速率,B项错误;泡沫灭火器中的成分为NaHCO3与Al2(SO4)3,工作时AI3+和HCO3发生双水解,C项正确;向氨水中不断通入CO2,随着CO2的增加,c(NH4)逐渐增大,而氨水中太=黑不变放,0的值不斯谈小D项铝误。11.D【解题分析】由于H2R的K1和K2均大于H2SO3的K2,因此1molH2R最多能与2molNa2SO3反应生成NaHSO3,A项错误;NaHR溶液中存在水解衡和电离衡,且电离常数大于水解常数,其溶液呈酸性,B项错误;根据H2R和H2SO3的电离衡常数可知,将二氧化硫通入酒石酸钠溶液中只能生成亚硫酸氢钠,C项错误;等物质的量浓度的KHR和K2R的混合溶液中,根据元素质量守恒可知,2c(K+)=3c(H2R)十3c(HR)十3c(R-),D·53·【24·G3DY(新高考)·化学·参考答案一R一必考一HEB】
