What is the difference between Ksp and Qsp?
Ksp: The solubility product constant, an equilibrium constant. Qsp: The ion product, calculated using initial concentrations to predict precipitation.
What are the steps to calculate Ksp from solubility (g/L)?
1. Write the dissolution reaction. 2. Convert solubility from g/L to mol/L (Molarity). 3. Plug molarity into the Ksp expression: Ksp = [ion1]^coefficient * [ion2]^coefficient.
What are the steps to calculate molar solubility from Ksp?
1. Write the dissolution reaction. 2. Set up a RICE table. 3. Plug equilibrium concentrations (in terms of 'x') into the Ksp expression. 4. Solve for 'x', which represents the molar solubility.
How do you predict precipitation using Qsp and Ksp?
1. Calculate Qsp using initial ion concentrations. 2. Compare Qsp to Ksp: If Qsp > Ksp, precipitation occurs. If Qsp < Ksp, no precipitation occurs. If Qsp = Ksp, the solution is at equilibrium.
What is the effect of a high Ksp value on the solubility of a compound?
A high Ksp value indicates that the compound is highly soluble.
What is the effect of Qsp > Ksp?
Precipitation occurs; the solution is supersaturated.
What is the effect of Qsp < Ksp?
No precipitation occurs; the solution is unsaturated.
What is the effect of Qsp = Ksp?
The solution is at equilibrium (saturated).
