Does common ion effect affect molar solubility?
Adding a common ion decreases solubility, as the reaction shifts toward the left to relieve the stress of the excess product.
What is the molar solubility of PbI2?
The molar solubility of PbI2 is 1.52 x 10-3 M.
What is the Ksp expression for PbI2?
Consider that the Ksp of PbI2 is 1.4 x 10-8.
Why does adding a common ion decrease solubility?
If you have a solution and solute in equilibrium, adding a common ion (an ion that is common with the dissolving solid) decreases the solubility of the solute. This is because Le Chatelier’s principle states the reaction will shift toward the left (toward the reactants) to relieve the stress of the excess product.
What affects molar solubility?
Solubility is affected by multiple factors. Solids becomes more soluble as temperature increases. As pressure increases, gases become more soluble. The common-ion effect describes a decrease in solubility of an ionic compound when the solution already contains an ion that is the same as one from the compound.
What is the water solubility of PbI2 in moles per liter?
explanation : The solubility of PbI2 in water is s mol/L. then we have to find concentration- solubility product. or simply say, solubility product. we know, PbI2 dissociates into Pb²+ and 2I- ions. hence, solubility product of PbI2 is 4s³.
What is the relation between molar solubility and solubility product for salt given below PbI2?
Answer: A substance’s solubility product (Ksp) is the ratio of concentrations at equilibrium. Molar solubility, which is directly related to the solubility product, is the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
What is solubility product and common ion effect?
Adding a common ion decreases the solubility of a solute. The common-ion effect can be used to separate compounds or remove impurities from a mixture. Different common ions have different effects on the solubility of a solute based on the stoichiometry of the balanced equation.
Which action will decrease the solubility of PbI2?
The presence of a common ion would reduce the solubility of PbI2.
