Answer 1

Answer #1

Initial Concentration of Hg²⁺ after mixing = 0.0026M/2 = 0.0013 M and concentration of NH₃ = 0.20/2 = 0.10M

As formation constant is very large , most of Hg²⁺ would convert into complex form .

Hg²⁺ +. 4 NH₃ $\leftrightharpoons$ . [Hg(NH₃)₄]²⁺ K_f = 1.8×10¹⁹

x. (0.1-0.0013×4)M. 0.0013M

1.8×10¹⁹ = 0.0013/(x * (0.0948)⁴)

x = 0.0013/(0.0948⁴ × 1.8×10¹⁹) = 8.942×10^-19

[Hg²⁺] = 8.9×10^-19 M. (Answer)
