Question

At 25 ?C, the osmotic pressure of a solution of the salt XY is 60.8torr . What is the solubility product of XY at 25 ?C?

Answer #1

XY(s) ----------> X^{+}(aq) + Y^{-}(aq)

Now, Osmotic pressure, P (in atm) = i*Molar concentration of XY*R*T ;

where R = universal gas constant = 0.0821 ; T = temperature in kelvin = 298 K ; i = Van't Hoff's factor =2 as XY completely dissociates into its respective ions

760 torr = 1atm

Now, (60.8/760) = 2*molar concentration*0.0821*298

or, molar concentration = 1.635*10^{-3} M

now, Molar concentration of X^{-}, [X^{-}] =
Molar concentration of Y^{-}, [Y^{-}] = Molar
concenmtration of XY = 1.635*10^{-3} M

Thus, K_{sp} = [X^{-}][Y^{-}] =
2.673*10^{-6}

The solubility of the salt MxAy is 1.0 ´ 10-2 mol/L at 25°C. The
osmotic pressure exhibited by a solution saturated with MxAy at
25°C is 1.22 atm. Determine the values of x and y by assuming ideal
behavior.

A) In reverse osmosis, water flows out of a salt solution until
the osmotic pressure of the solution equals the applied pressure.

The osmotic pressure of 100.0 mL of a 25 C solution containing
0.50 g of a protein is 5.8 Torr. Based on this information,
determine the molar mass of the protein in g/mol.
Hint: The protein does not dissociate in water;
thus the Van't Hoff factor equals 1.
