When a river flows through deposits or bedrock containing minerals with Hg, the Hg has the potential to be released into solution. Assume that a river concentration of 4^2= 0.5mol/L, = 0.002 mol/L, and 2is <<0.001 mol/L. If the riverbanks have local deposits of the solids/minerals listed in the table below should we be concerned that the deposits are dissolving and significantly adding to the total Hg concentrations in the river? Explain why or why not with a few calculations and sentences.

Mercury(I) chloride Hg2Cl2 1.43 1018

Mercury(I) sulfate Hg2SO4 6.5 107

Mercury(II) sulfide HgS 4 1053
