The solubility of copper(i) chloride is 3.91 mg per 100.0 ml of solution. calculate ksp for cucl (cucl=99.00 g mol-1).

Answer : The value of is

Explanation :

First we have to calculate the mass of CuCl in 1 L or 1000 mL solution.

As, 100.0 mL of solution contains 3.91 mg of CuCl

So, 1000 mL of solution contains of CuCl

The mass of CuCl = 39.1 mg = 0.0391 g

conversion used : (1 mg = 0.001 g)

Now we have to calculate the moles of CuCl.

Molar mass of CuCl = 99.00 g/mol

Now we have to calculate the moles of and ion.

Moles of = Moles of = Moles of CuCl =

Thus, the concentration of and ion in 1 L solution will be:

= =

Now we have to calculate the value of for CuCl.

The solubility equilibrium reaction will be:

The expression for solubility constant for this reaction will be,

Therefore, the value of is
