Calculate, the following. (i) Ratio of '[Ag(NH3)2]+' and '[A g+]' in '0.1 M' 'NH3' solution. (ii) Ratio of '[Ag(S2 O2)2]3' and '[Ag+]' in '0.1 M' 'S2 O3^2-' solution. Given that the stability-formation constants for '[Ag(NH3)2]^+' and '[Ag(S2 O3)2]^3' are '1.7 x 10^7' and '1 x 10^13' respec- tively.

Explanation

(i) Ag^+ 2 NH_3 stackrelKf/harpoons[Ag(NH_3)_2]^*
k_f=[Ag(NH_3)_2]^+/[Ag^+][NH_3]^2=1.7 xx 10^7
therefore [Ag(NH_3)_2]^+/[Ag^+]=1.7 xx 10^7 xx(0.1)_i^2
therefore =1.7 xx 10^5
