The hydroxide ion has the formula OH-. The solubility-product constants for three generic hydroxides are given here. XOH = 2.90 x 10-8 Ksp Y(OH)2 = 2.20 x 10-10 Ksp Z(OH)3 = 8.20 x 10-15 Ksp The removal of an ion is sometimes considered to be complete when its concentration drops to 1.00 x 10-6 M. What concentration of hydroxide would cause Y+2 to "completely" precipitate from a solution?

1. Terry is a scientist who wants to examine the properties of a newly discovered substance. The substance appears to be organic based therefore, Terry feels as if the substance can be easily broken down by macromolecules. Terry decided to incubate the substance with a cell extract that contain several different types of macromolecules. After a one-hour incubation the substance has been broken down in the same way molecules are broken down by proteases. However, upon further inspection of the...
