计算lgK´MY (1)pH=5.0,lgK´ZnY (2)pH=10.0 lgK´AlY

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.
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(NH3) 及aNi(CN) ,两者相加得 Ni的总副反应系数lgaNi,lgK'NiY = lgKNiY-lgaY(H)-lgaNi.
