在 AgNO 3 饱和溶液中,加入 NaCl 固体,达平 .. ..................................... ( ) (A) c ( Ag + ) = c ( Cl - ) ; (B) c ( Ag + ) = c ( Cl - ) = [ K sp θ ( AgCl ) ] 1/2 ; (C) c ( Ag+ ) ≠ c (Cl - ) , [ c (Ag + ) / c θ ]·[ c (Cl - ) / c θ ] = K sp θ ( AgCl ) ; (D) c ( Ag + ) ≠ c (Cl - ) , [ c (Ag + ) / c θ ]·[ c (Cl - ) / c θ ] 1 K sp θ ( AgCl ) 。
