Enter the the Ksp expression for the solid AB2 in terms of the molar solubility x. express your answer in terms of x.
♦ Relevant knowledge

The degree that the salt dissolves in solution is called its solubility. The degree of solubility is determined by a variety of variables, including the chemical composition of the solvent and salt as well as the pressure and temperature of the system, and so on. When a common-ion is present salt, the solubility of the salt decreases.

    Concepts and Reason

    This concept is used to determine the solubility constant expression of the salt given in x.

    Fundamentals

    , the solubility product, is the equilibrium constant of a solid that dissolves in a solution. It is the sum of the products’ concentrations multiplied by their coefficients.

    Take a look at M.X,(s) aM* (aq) +bX“ (aq) as a general reaction.

    This is the expression for the solubility constant of the reaction:

    K«=[M] [x°-]

    The given salt is .

    This is the dissociation reaction:

    AB,(s) = A + (aq) +2B (aq)

    This is the expression for the solubility products:

    [-a] «zv]= y

    Let , have a molar solubility of and be .

    For the reaction, create an ICE table.

    A+ (aq)+2B (aq) AB,(s) Initial: Change: Equilibrium: + +2x 2x

    This is the expression for the solubility products in x:

    K.5 =[x][2x]

    Ans:

    The expression for is .
