常温下,0.1 mol·L—1氨水溶液中c(H+)/c(OH—)=1×10—8,下列叙述正确的是

A.该溶液中氢离子的浓度:c(H+ ) = 1×10—9 mol·L—1

B.常温下,NH4Cl和NH3·H2O的混合溶液[pH=7,c(Cl- )=" 0.1" mol·L—1]中:

c(Cl—) >c(NH4+ ) > c(H+ ) =c(OH-)

C.0.1 mol·L—1 的氨水溶液与0.05 mol·L—1 H2SO4溶液等体积混合后所得溶液中:

c(NH4+ ) + c(NH3) + c(NH3·H2O) = 2c(SO42—)

D.浓度均为0.1mol·L—1 的NH3·H2O和NH4Cl溶液等体积混合后,若溶液呈碱性,则c(NH4+ )> c(NH3·H2O) > c(Cl—) > c(OH-) > c(H+ )
