Question
which salt will precipitate first, calcium fluoride or magnesium fluoride when 0.10 M NaF solution is slowly added to a solution that is 0.10M with respect to both initial salts? (Ksp for CaF2=4.0X10^-11, Ksp for MgF2=6.4X10^-9) which salt will precipitate first, calcium fluoride or magnesium fluoride when 0.10 M NaF solution is slowly added to a solution that is 0.10M with respect to both initial salts? (Ksp for CaF2=4.0X10^-11, Ksp for MgF2=6.4X10^-9) which salt will precipitate first, calcium fluoride or magnesium fluoride when 0.10 M NaF solution is slowly added to a solution that is 0.10M with respect to both initial salts? (Ksp for CaF2=4.0X10^-11, Ksp for MgF2=6.4X10^-9)Explanation / Answer
Compare the Ksp values of both CaF2 and MgF2. Among these one which is having least Ksp will precipitate first
Ksp(CaF2)=4.0X10-11 (least value)
Ksp(MgF2)=6.4X10-9
Therefore CaF2 (calcium fluride) will precipitate first
