(i)Estimate the solubility of hydrogen in water at the given temperature and
pressure.
Would I use Henry's law for this? so p=1atm/101325Pa
So C = kH x p
I know kH = 1282.05 L atm mol-1 from Wikipedia but not sure that's how I'm supposed to do it!
1282.05 x 1 = 1282.05
Think I'm definitely doing this wrong??
(ii)Given that Eo Ag+/Ag is 0.7990 V at 25°C, give the Eo of the cell and
determine the molality required to produce unit activity of H+. Give full working and reasoning in your answer, explaining any assumptions you make.
No idea what I'm doing here! So Eocell = Eanode - Ecathode and I'm given Ecathode as 0.7990 V. Is the standard hydrogen cell always ) 0 V? Then I'm guessing when I work out Ecell I would draw a graph of molarity vs E and work out the molarity?
