Question
Give the equation for a saturated solution in comparing Q with Ksp.
Group of answer choices:
Q < Ksp
Q > Ksp
Q ≠ Ksp
Q = Ksp
none of the above
Solution
The equation for a saturated solution in comparing Q with Ksp is Q = Ksp.
Here's why:
Q is the reaction quotient, which measures the relative amounts of products and reactants present during a reaction at a particular point in time.
Ksp is the solubility product constant, which is a measure of how much of a particular compound can dissolve in solution.
When a solution is saturated, it means that the maximum amount of solute has been dissolved in the solvent at a given temperature. At this point, the rate of dissolution and precipitation are equal, so the concentrations of the reactants and products are not changing.
Therefore, in a saturated solution, Q (the ratio of the concentrations of the products to the reactants at that moment) is equal to Ksp (the ratio of the concentrations of the products to the reactants at equilibrium). So, Q = Ksp.
