Calculate the concentration of free mercury (II) ion, [Hg²⁺], in an aqueous solution that is initially 0.16 M Hg(NO₃)₂ and 3.2 M NaCl given that the K_f of HgCl₄^2- is 1.7*10¹⁶.

The answer is 2.2*10^-19 M, how?

Expert Solution

The equation for the complexation reaction is

Hg⁺² + 4 Cl^- -------> [HgCl₄]^-2

0.16M 3.2M 0 initial concentrations

0.16-x 3.2-4x x after reaction

Thus Kf = x/[(0.16-x)(3.2-4x)⁴ which is equal to 1.7 x 10¹⁶

Soving for x we get
