Question

The solubility product of iron (III) hydroxide is 1.6 cross times 10 to the power of negative 39 end exponent. If X is the solubility of iron (III) hydroxide, which one of the following expression can be used to calculate X?

  1. K subscript s p end subscript equals X to the power of 4 end exponent  
  2. K subscript s p end subscript equals 9 X to the power of 4 end exponent  
  3. K subscript s p end subscript equals 27 X to the power of 3 end exponent  
  4. K subscript s p end subscript equals 27 X to the power of 4 end exponent  

The correct answer is: K subscript s p end subscript equals 27 X to the power of 4 end exponent


    The solubility product (K subscript s p end subscript) of a sparingly soluble salt at a given temperature may be defined as the product of the molar concentrations of its ions each raised to the power equal to its number of ions present in the equation representing the dissociation of one molecule of the salt.
    F e open parentheses O H close parentheses subscript 3 end subscript rightwards harpoon over leftwards harpoon F e to the power of 3 plus end exponent plus 3 O H to the power of minus end exponent
    X X 3 X
    K subscript s p end subscript equals open square brackets F e to the power of 3 plus end exponent close square brackets open square brackets O H to the power of minus end exponent close square brackets to the power of 3 end exponent
    therefore K subscript s p end subscript equals X open parentheses 3 X close parentheses to the power of 3 end exponent equals 27 X to the power of 4 end exponent
