At 25 °C, an aqueous solution has an equilibrium concentration of 0.00423 0.00423 M for a generic cation, A + A+ (aq), and 0.00423 0.00423 M for a generic anion, B − B− (aq). What is the equilibrium constant, K sp Ksp , of the generic salt AB (s)

Answer : The value of of the generic salt AB is,

Explanation : Given,

Concentration of generic cation, = 0.00423 M

Concentration of generic anion, = 0.00423 M

The equilibrium chemical reaction will be:

The solubility constant expression for this reaction is:

Now put all the given values in this expression, we get:

Thus, the value of of the generic salt AB is,
