Question

The solubility of copper(I) chloride is 3.91 mg per 100.0 mL of solution. Calculate Ksp for CuCl.

Answer 1

697-16-94P SA: 5276

SR: 4481

Data:

Volume of solution = 100.0 mL

Mass of CuCl = 3.91 mg

= 0.00391 g

Molar mass of CuCl = 99.0 g / mol

=

Concentration of CuCl=

=

=

Concentration of CuCl=

=

Chemical equation:

I (M) 0 0

C (M) +s +s

E (M) +s +s

Expression for Ksp =

=

=

Upon substituting the value of s in the above expression,

Ksp =

=
