Question- Part 1) Determine the speciation of manganese when 2*10^6 M Mn(NO3)2 added to water at pH 6 and at pH 9. Assume that the manganese does not participate in any redox reactions but remains whooly as Mn^11. Solve manually using the thermodynamic data in Table 9.3 or use MINEQL+ or another computer equilibrium program.

Part 2) Repeat previous problem when 0.1 M NaCl is present. Consider activity corrections.

If possible just a brief explanation how you got the answer?
