Determine the concentrations of hg22 and cl– in a saturated solution of hg2cl2 in a. pure water (assume μ = 0).

To solve this, we need the solubility constant for Hg2Cl2, which is:

Ksp = 1.4 x 10^-18

The ionic formula would be:

Hg2Cl2(s)  --->  Hg2 2+(aq) + 2Cl-(aq)

 

Therefore the total amounts of ions produced = x M Hg2 2+ and 2x M Cl- 

The formula for Ksp in this case is:

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

1.4 x 10^-18 = (x) * (2x)^2

1.4 x 10^-18 = 4x^3
x = 7.0 x 10^-7 M = [Hg2 2+]

2x = 14 x 10^-7 M = [Cl-]

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
