WIll give 5 stars! Please show work and correct answer!

1) Given the following equilibrium Hg2Cl2(s) --> Hg2^2+ (aq) + 2Cl- (aq)    

Ksp= 1.2x10^-18

Determine the concentrations of Hg2^2+ and Cl- in a saturated solution of Hg2Cl2 in a solution with an ionic strength of 0.010

[Hg2^2+]=

[Cl-]=

Determine the concentration of Hg2^2+ and Cl- in a saturated solution of Hg2Cl2 in a solution with an ionic strength of 0.10

[Hg2^2+]=

[Cl-]=

2) Ignoring activities, determine the molar solubilty of copper (I) azide (CuN3) in a solution with a

pH= 11.92

Ksp= 4.9 x 10^-9

Ka (HN3)= 2.2 x 10^-5

Explanation / Answer

1. Ksp = [Hg2^2+] [Cl-]^2

1.2x10^-18 = [Hg2^2+] [2Hg2^2+] ^2,

1.2x10^-18 = 4 [Hg2^2+] ^3

[Hg2^2+] = 6.694 *10^-7

[Cl-] = 2* [Hg2^2+] =1.339*10^-6

for 0.1 ionic strength ,

also ,

[Hg2^2+] = 6.694 *10^-7

[Cl-] = 2* [Hg2^2+] =1.339*10^-6
