Question 9#

Which of the following is FALSE regarding biochemical pathology of urine in patients with kidney stones?

A. A solution containing ions or molecules of a sparingly soluble salt is described by the concentration product, which is a mathematic expression of the product of the concentrations of the pure chemical components (ions or molecules) of the salt
B. The concentration product, the point at which the dissolved and crystalline components are in equilibrium for a specific set of conditions, at the point of saturation is called the stability product, Ksp
C. The Ksp value and the formation product (Kf) differentiate the three major states of saturation in urine: undersaturated, metastable, and unstable
D. The concentration product at the point where the crystals can no longer be held in solution is called the formation product, Kf
E. Inhibitors can generally prevent the process of crystal growth or aggregation above the formation product, Kf

Correct Answer is B

Comment:

Answer B

The concentration product, the point at which the dissolved and crystalline components are in equilibrium for a specific set of conditions, at the point of saturation is called the thermodynamic solubility product, Ksp. Inhibitors can generally prevent the process of crystal growth or aggregation above the formation product, Kf.
