BaSO4 is easily separated.
Because BaSO4 have lowest solubility product (Ksp).
BaSO4 ..........> Ba^2+ + SO42-
Ksp = [Ba2+][SO42-] = s * s = s^2
where s = molar solubility of BaSO4.
thus
lowest solubility indicate the lowest molar solubility.
Hence
BaSO4 is easily separated.

Use the given Kan values to predict which of the following salts is the most soluble, in terms of moles per liter, in pure water. (Hint: The size of Ksp tells us about solubility in general. The tutorial will explain the math but comparing the values for the general solubility is sufficient for these since they are all 1:2 ratios of ions.) Special note: mercury(I) ions forms a dimer and behaves like a polyatomic ion. So, Hg,X, breaks into Hg,...

You will be making observations on the results of binary mixing from a total of seven known solutions. From your observations and your knowledge of chemical behavior and solubility. you identify the identity of each of the nine unmarked solutions. As you can probably already see, careful observations, recording of results and deductions will be the key to success....
