Chapter 8, Problem 10DQ

A friend tells you: "The constant $K_{\text{sp}}$ of a salt is called the solubility product constant and is calculated from the concentrations of ions in the solution. Thus, if salt A dissolves to a greater extent than salt $B,$ salt A must have a higher $K_{\text{sp}}$ than salt $B."$ Do you agree with your friend? Explain.
