把0.02mol/L CH3COOH溶液和0.01mol/L NaOH溶液等体积混合,则混合溶液中微粒浓度关系,正确的是( ) A.c ( CH3COO - )>c(Na+) B.c(CH3COOH)>c (CH3COO-) C.2c(H+)= c(CH3COO - )—c(CH3COOH) D.c(CH3COOH)+c
A
两者混合后,形成缓冲溶液,因为c(HAc)/c(Ac-)=1
所以溶液的PH=PKa=4.76 呈酸性,所以有c ( CH3COO - )>c(Na+)

把0.02mol/L CH3COOH溶液和0.01mol/L NaOH溶液【急!】尤其是A为啥对啊. 把0.02mol/L CH3COOH溶液和0.01mol/L NaOH溶液以等体积混合,混合溶液中粒子浓度将0.02mol/L CH3COOH溶液和0.01mol/L NaOH溶液以等体积混合,混合溶液中粒子浓度关系正确的( ) A:C(CH3COO-)>C(Na+)B:C(CH3COOH) 把0.02mol/L CH3COOH溶液和0.01mol/L NaOH溶液以等体积混合,物料守恒的式子怎么写 6.14-化学/P110(11).把0.02mol/L CH3COOH 溶液与0.01mol/L NaOH 溶液 等体积混合,则溶液中微粒浓度关系正确的是()?A.c(CH3COO-)>c(Na+)B.c(CH3COOH)>c(CH3COO-)C.2c(H+)=c(CH3COO-)-c(CH3COOH)D.c(CH3COOH)+c(CH3COO-)>0.01mol/L为什 把0.02mol/L CH3COOH 溶液与0.01mol/L NaOH 溶液 等体积混合,则溶液中微粒浓度关系正确的是(多选)A.c(CH3COO-)>c(Na+)B.c(CH3COOH)>c(CH3COO-)C.2c(H+)=c(CH3COO-)-c(CH3COOH)D.c(CH3COOH)+c(CH3COO-)=0.01mol/L 把0.02mol·L-1CH3COOH溶液与0.01mol·L-1 NaOH溶液等体积混合,把0.02mol·L-1CH3COOH溶液与0.01mol·L-1NaOH溶液等体积混合,混合后溶液显酸性则混合液中微粒浓度关系不正确的是( C)A.c(CH3COO-)>c(Na+) B.c(H+)+c 把0.02 mol/L CH3COOH溶液与 0.01mol/LNaOH溶液等体积混合,则 混合液中微粒浓度关系正确的是( )A、c(CH3COO-)>c(Na+) B、c(CH3COOH)>c(CH3COO-)C、2c(H+)=c(CH3COO-)-c(CH3COOH) D、c(CH3COOH)+c(CH3COO-)=0.01 mol/L 把0.02mol/L CH3COOH溶液和0.01mol/L NaOH溶液等体积混合,则混合溶液中微粒浓度关系,正确的是( ) A.c ( CH3COO - )>c(Na+) B.c(CH3COOH)>c (CH3COO-) C.2c(H+)= c(CH3COO - )—c(CH3COOH) D.c(CH3COOH)+c 把0.02 mol/L CH3COOH溶液与 0.01mol/LNaOH溶液等体积混合,则 混合液中微粒浓度关系正确的是( )A、c(CH3COO-)>c(Na+) B、c(CH3COOH)>c(CH3COO-)C、2c(H+)=c(CH3COO-)-c(CH3COOH) D、c(CH3COOH)+c(CH3COO-)=0.01 mol/LC选项是 0.02mol/L的CH3cooH和0.01mol/L的NaOH等体积混合,混合后的溶液离子关系是?c(CH3COOH)+c(CH3COO-)=0.01mol 把0.02mol/LCH3COOH溶液和0.01mol/LNaOH溶液等体积混合为什么混合后,混合液的溶质为CH3COOH和CH3COONA且物质的量相等,都为5*10^-3mol/l? 混合溶液的物料守恒书写如0.02mol/L CH3COOH溶液和0.02mol/L /L CH3COONa溶液等体积混合,怎么写物料守恒? 1L 1mol/L CH3COOH溶液中,所含CH3COO-、CH3COOH的总数为1mol? 1mol/L HCL溶液,1mol/L H2SO4溶液,1mol/L NAOH溶液,1mol/L CH3COOH c(H+)溶液,浓度大小排到急!急! 0.1mol/LNaOH溶液与0.1mol/L的CH3COOH溶液那个的PH大? 物质的量浓度0.01mol/L的CH3COOH和CH3COONa的混合溶液中:c(CH3COOH)+c(CH3COO-)=0.01mol/l,错哪了?难道是0.02mol/L? 把0.02mol/LCH3COOH溶液和0.01mol/LNaOH溶液以等体积混合,则混合液中微粒浓度关系正确的为?(双选)A,c(CH3COO-)>c(Na+)B,c(OH-)>c(H+)C,c(CH3COOH)>c(CH3COO-)D,c(CH3COOH)+c(CH3COO-)=0.01mol/L要解释.~~ 把2gNaOH固体分别加入到下列100ml的溶液中,溶液的导电性基本不变的是A.0.5mol/L NaCl B.0.5mol/L HClC.0.5mol/L CH3COOH D蒸馏水小弟不懂
