问题描述：
计算lgK´MY (1)pH=5.0,lgK´ZnY (2)pH=10.0 lgK´AlY
(3)pH=9.0 [NH3]+[NH4+]=0.20mol/L,[CN-]=10的-5次方mol/L lgK'NiY
求教阿阿阿阿~急.
答
提示：(1) 查 pH=5.0时,lgaY(H),则 lgK'ZnY=lgKZnY-lgaY(H)；（2）查 pH=10.0时,lgaY(H)及lgaAl(OH),则 lgK'AlY=lgKAlY-lgaY(H)-lgAl(OH)；(3)查 pH=9.0时,lgaY(H) ,求pH=9.0 时[NH3]的浓度,求 Ni的副反应系数aNi(NH...
