1. What is the molar solubility(M) of PbBr2 in pure water?
2. What is the molar solubility(M) of PbBr2 in 0.500M KBr solution?
3. What is the molar solubility(M) of PbBr2 in a 0.500M Pb(NO3)2 solution?

Concepts and reason
Solubility:
Solubility is defined as the maximum quantity of solute dissolved in a given amount of solvent to make a saturated solution at a particular temperature.

Molar solubility:
Molar solubility is the number of moles of a solute that can be dissolved in one liter of a solution. It is expressed as mol/L or M (molarity).

Common ion effect:
Common ion effect is defined as the solubility of a partially soluble salt which will decrease with the addition of a soluble salt that has an ion in common with it.

Fundamentals
Consider a general reaction:

The relation between solubility product and molar solubility is as follows:

Answer:

Therefore, the molar solubility (M) of in pure water is .

Explanation
The given compound is slightly soluble in water and the solubility product constant is . The molar solubility (M) of in pure water is calculated using the solubility product expression.
