Question

A fictional compound AX₂ has a molar mass of 152.01 g/mol and a Ksp of 5.6237e-10. It dissociates in water based on the equation:
AX_2(s) ⇔ A²⁺_(aq) + 2X^-_(aq)
Based on this information, label the statements below as true or false.

    The mass solubility of AX₂ is less than 1.52E-2 g/100mL H₂O.
    If the solution is heated and the solubility increases, then the heat of solution for AX₂ is exothermic.
    If soluble NaX is added to the system then [A²⁺] will increase.
    The molar solubility of AX₂ is greater than 2.40E-4 mol/L.
    If more soluble A(NO₃)₂ is added to the system then [X^-] will decrease.
    If more solid AX₂ is added to the system then [X^-] will increase.
    If more solid AX₂ is added to the system then [A²⁺] will increase.
