Conductivity of HCl,LiCl,NaCl and KCl
« on: August 18, 2008, 03:49:54 PM »
I carried out the experiment on electrical conductance of electrolytes and then the molar conductivity of each cation was calculated...The order of their conductivity in increasing order was..Li+, Na+, K+, H+.Then I was asked to account for the differences between the conductances of these cations.
Can i take into account the density charges in the discussion? If so, how can i explain the fact that H+ has much larger charge density than Li+ yet it has higher conductances?

Your help will be highly appreciated.
Thanks.

H+ mobility is exceptionally large as its charge can jump between water molecules (think in terms about hydrogen bonding) - so charge moves much fasetr then the proton does.
