Question

KH for H2 (g) / water system is 5.34*107 torr. If the partial pressure of H2, over a solution at 25°C is 760 torr, then determine the solubility of hydrogen.
Assume density of H2O and solutions are same
(1) 6.4 x 10-3 mol L-1
(2) 7.89 x 10-4 mol L-1
(3) 5.9 ~ 10-3 mol L-1
(4) 8.9 x 10-4 mol L-1​

Answer 1

Answer:

Henry's law states that :

where p = partial pressure of the gas above the solution.

    is the Henry's solubility constant for the solvent & solute at given T°C

   c = molar concentration  of the solute in the solution in  moles/Litre  at given T°C

p = 1 bar    and    =71.18 kbar-Litre/mol

  c = 1  / 71.18 * 10³ = 14.048 mol/Litre

 concentration =  14.048 mol/Litre  or    28.096 gms/Litre
