The ksp of pbbr2 is 6.60×10−6. What is the molar solubility of pbbr2 in pure water?

Answer : The molar solubility of in pure water is, 0.0118 M

Explanation :  Given,

The solubility equilibrium reaction will be:

Let the molar solubility be 's'.

The expression for solubility constant for this reaction will be,

Now put all the given values in the above expression, we get:

Therefore, the molar solubility of in pure water is, 0.0118 M

fe 55.85 g/mol and h2o 18.02 g/mol.
