Gout is caused by an error in metabolism that leads to abuildup of uric acid in body fluids, which is deposited as slightlysoluble sodium urate (C₅H₃N₄O₃Na) in the joints. If the extra-cellular [Na⁺] is 0.15 Mand the solubility of sodium urate is0.085 g/100. mL, what is the minimum urate ion concentration(abbreviated [Ur⁻]) that will cause a deposit of sodium urate?
The simple form of |Hoff equation is:
II = [B]RT
In this equation the [B] is the molar concentration of solute. So:
n
m
[B] =
v MV
= cg /MA
Where c, the mass concentration of the solute is in the total volume of solution and M, is the molar mass of the solute. This equation can be
replaced in the previous one to get:
RT
II =
MA
In this equation molar mass of given solute can be detemined from the slope of the II vs Cz plot. This equation applies only to solutions that are
sufficiently dilute to behave as ideal-dilute solutions. In the case of non-ideal solutions, however, the extended formula is:
II = [B]RT{1+ k. [B] + n. [B]² + ...}
Biological macromolecules dissolve to produce solutions that are far from ideal, but we can still calculate the osmotic pressure by assuming that
the van't Hoff equation is only the first term of a lengthier expression:
II [B]RT(1+ b. [B])
II
= RT + bRT. [B]

II
= RT + bRT./M.
