What if QSP is greater than KSP?
When QSP is greater than KSP, the solution is oversaturated. So it’s exceeded the limit of what can dissolve, and therefore you can imagine some lead two plus ions combining with some sulfate ions to form a precipitate. Therefore, when QSP is greater than KSP, a precipitate will form.
When QSP KSP then a solution is?
Step 4: Compare Qop with Ksp : in this case Qsp > Ksp : the solution is supersaturated and a precepetate will form until the concentrations of the ions satisfy the solubelity product expuession.
What happens if Q is less than K?
If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants.
Does high KSP mean higher solubility?
The solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution. The value of the constant identifies the degree to which the compound can dissociate in water. The higher the Ksp, the more soluble the compound is.
How do I calculate Ksp?
Ksp is constant at a given temperature (van’t Hoff equation) for a saturated solution of a given compound.
- Problem: Write the Ksp expression for the following weak electrolytes: Mn(OH)3(s), Sr3(AsO4)2(s), and Co2S3(s).
- Calculating Solubility from Ksp:
- Ksp = [Ca2+][F-]2 = [2.14×10-4][4.28×10-4]2 = 3.9 x 10-11
What is QSP solubility?
What is Qsp? Qsp is the solubility product quotient of a solution. It describes the current state of a solution. This means Qsp is given for an unsaturated (before saturation), saturated or a supersaturated solution.
What is QSP?
Qsp is the solubility product quotient of a solution. It describes the current state of a solution. This means Qsp is given for an unsaturated (before saturation), saturated or a supersaturated solution.
How do you find solubility from KSP?
How do you find solubility from KSP? Set up an ICE problem (Initial, Change, Equilibrium) in order to use the Ksp value to calculate the concentration of each of the ions. The concentration of the ions leads to the molar solubility of the compound.
How do you calculate solubility and KSP?
• Calculating Solubility from Ksp Write rxn: CaF2 (s) ⇌ Ca2+ (aq) + 2 F– (aq) 2. Write Ksp: Ksp = [Ca2+] [F–]2 = 3.9 × 10–11 3. What is the solubility of CaF2 in pure water at 25? The molar solubility of CaF2 at 25C in pure water is 2.1*10^-4M. Which expression will give the molar solubility of CaF2 at 25? calculate Ksp of CaF2 at this temperature.
What is the difference between solubility and KSP?
If the Qsp value is less than the Ksp for a substance in a solution,more solids can be dissolved in that solution.
