If two salts AX and BX2, have the same Ksp values of 4.0x10^-12 at a given temperature, then

A. their molar solubilities in water are the same
B. the salts are more soluble in 0.1 M NaX than in water
C. the molar solubility of AX in water is less than that of BX2
D. addition of NaX will not affect the colubilities of the salt.

  1. which do you think is correct and why? I suggest you make up problems and work each one; for example, see if A is a true statement.
    AX ==> A^+ + X^-
    Ksp = (x)(x) = 4 x 10^-12
    x= sqrt 4 x 10^-12 = 2 x 10^-6 M

    AX2 ==> A^+2 + 2X^-
    Ksp = (x)(2x)^2 = 4 x 10^-12
    4x^3 = 4 x 10^-12
    x = 1 x 10^-4 M
    So they are not the same and A is not true. ETC. For the common ion in B, just use 0.1 M NaX.

  2. well C says AX is less than BX2 and it is so i thought it would be that one.
