Homework Help: Will a precipitate form if I do this

  1. Jun 12, 2005 #1
    I'm working on a chem problem for my exam tommorow. Can anyone help me?
    Q1: Will a precipitate form if 45cm3 of 0.0035M NaI is added to 95cm3 of 0.0013M Pb(NO3)2? The Ksp of PbI2 is 7.08 x 10^-9.

    My teacher says the answer's no precipitate and the trial Ksp is 8.8 x10^-10. But I got 1.1 x 10^-9. Can someone show me how to do this? :frown:
