What is the relationship between KSP and solubility?
Ksp (Solubility product constant) is the equilibrium between a solid and its respective ions in a solution. The value of the constant identifies the degree of which the compound can dissociate in water. For example the higher the Ksp the more soluble the compound is.
What is the KSP formula?
Let’s do an example: The solubility of Ag2CrO4 in water is 1.31 x 10-4 moles/L. Calculate the value of Ksp . Using mole ratios, the [Ag+] will go up by (2 x 1.31 x 10-4 moles/L) = 2.62 x 10-4 moles/L.
How does KSP compare to solubility?
The relative MOLAR solubility of salts (saturated solution) can be determined by comparing Ksp values. The greater the Ksp the more ions are in solution, hence the greater the molar solubility.
How do you calculate GL solubility?
(Sometimes the data is given in g/L. When that happens, this step is skipped.) 2) divide the grams per liter value by the molar mass of the substance. This gives moles per liter, which is molar solubility.
What is the solubility of Al OH 3 in the presence of 0.2 M NaOH?
The molar solubility of Al(OH)_(3) in 0.2 M NaOH solution is x xx 10^(-22)”mol/L”. Given that, solubility product of Al(OH)_(3)=2.4xx10^(-24).
What are the 4 factors affecting solubility?
Factors affecting solubility
- Temperature. Basically, solubility increases with temperature. …
- Polarity. In most cases solutes dissolve in solvents that have a similar polarity. …
- Pressure. Solid and liquid solutes. …
- Molecular size. …
- Stirring increases the speed of dissolving.
What is the unit for KSP?
Actually, it doesn’t have a unit! The K s p value does not have any units because the molar concentrations of the reactants and products are different for each equation.
How do I calculate ka?
Dissociation Constant for Acetic Acid
Since x = [H3O+] and you know the pH of the solution, you can write x = 10–2.4. It is now possible to find a numerical value for Ka. Ka = (10–2.4)2 /(0.9 – 10–2.4) = 1.8 x 10–5.
What is solubility product?
The solubility product constant, Ksp, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. The more soluble a substance is, the higher the Ksp value it has.
What affects solubility?
Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
