Question “Determine the molar solubility of AgBr in a solution containing 0.150 M NaBr. Ksp (AgBr) = 7.7 × 10-13.”
Determine the molar solubility of AgBr in a solution containing
0.150 M NaBr. Ksp (AgBr) = 7.7 × 10-13.
Answer
This problem uses the solubility product as its basis.
With the help of expressions of solubility products, find the molar solubility for a particular compound in a specific solution.
Solubility product
The solubility product is basically the equilibrium between solids, and their respective ions in the solution. The solubility product is the amount of chemical compound that can be dissociated in water.
Exemple:
