A solution is made by adding 0.1 M HgSO4 to 0.15 M HCl plus 0.03 M NaCl. a. List the unknown species by looking at potential complexes in Tables 4.4 and 4.5. b. Write the mass balances for total Hg, SO4, and Cl. c. Write out the additional equations you would need to consider. d. Confirm that the number of equations is equal to the number of unknowns.
Note: You do not need to solve this problem, but you can clearly see how this lends itself to being solved by a computer.
