I just cant figure out this one or how to go about it please help!?
If NaF solution is added to a solution containing .1M Mg(NO3)2 and .1M Cr(NO3)3 will MgF2 or CrF3 precipitate first? Ksp= -6.6x10^-11 for Cr(NO3)3 First determine the amount of fluoride ion required to just begin precipitation for each compound.
