(Q56) Consider yttrium iodate, yttrium fluoride, lanthanum iodate, and gallium (II) hydroxide:
Yttrium iodate = Y(IO3)3 Ksp = 1.12 x 10-10
%3D
Yttrium fluoride = YF3
Ksp = 8.62 x 10-21
%3D
Lanthanum iodate = La(IO3)3 Ksp = 7.50 x 10-12
%3D
Gallium(III) hydroxide = Ga(OH)3 Ksp = 7.28 x 10-36
Which of the following statements is true regarding the solubilities of these compounds?
O They cannot be compared directly because their stoichiometry of dissociation is the same
O They cannot be compared directly because their stoichiometry of dissociation is different
O They can be compared directly - yttrium iodate is the most soluble
O They can be compared directly - gallium(III) hydroxide is the most soluble
O They cannot be compared directly because they have different cations and anions
