Ksp와 Q. Pb(NO3)2 and NaCl were each 0.020 M

 

 

Determine if a precipitate will form if the initial concentrations of Pb(NO3)2 and NaCl were each 0.020 M? (Ksp = 1.6×10^-5).

 

---------------------------------------------------

 

Q = [Pb^2+][Cl^-]^2

= (0.020) (0.020)^2

= 8.0×10^-6

 

 

Q < Ksp 이므로,

precipitate will NOT form.
