Question- A solution of Na2CO3 is added dropwise to a solution that is 8.70e-02 M in Nd3+and 6.88e-05 M in Hg22+.

• The Ksp of Nd2(CO3)3 is 1.08e-33.

• The Ksp of Hg2CO3 is 3.6e-17.

Calculate the concentration of CO32- present in the Nd3+ /Hg22+ solution when the first (initial) cation begins to precipitate and the concentration of CO32- present in this solution when the second (final) cation begins to precipitate. Write down which cation precipitates first and which precipitates second (last).

Explain each and every step in detail. I need proficient help in the above problems
