Practice: Ranking Solubilities
You have a series of beakers, each containing 100 mL of a different solution. If you added nickel (II) hydroxide (Ni(OH)2) to each of the beakers, rank them in order of the relative solubility of the Ni(OH)2 in each:

Additional Data:
A student adds some CuBr (s) (Ksp = 6.3x10βˆ’9) to each of the flasks shown here.
Assume that any salts in each flask were fully dissociated before CuBr(s) was added.
