What factors affect K equilibrium?
Temperature is the only factor that we learned affects K value. The direction of change in K value depends if the reaction is exothermic or endothermic. If the temperature increases, K will increase in an endothermic reaction and decrease in an exothermic reaction.

Is Ksp affected by concentration?
Ksp is defined in terms of activity rather than concentration because it is a measure of a concentration that depends on certain conditions such as temperature, pressure, and composition. It is influenced by surroundings.
Does Ksp change with concentration?
Solids are not included when calculating equilibrium constant expressions, because their concentrations do not change the expression; any change in their concentrations are insignificant, and therefore omitted. Hence, Ksp represents the maximum extent that a solid that can dissolved in solution.

What is the solubility of salt?
The solubility product of salt changes with temperature and the concentration of the ions present in solution . In oilfield brines, if the surface solubility produced is smaller than their solubility product under down-hole formation, scale formation would occur. Under such conditions, the water is called ‘unstable water.’.
What is the solubility product of calcium hydroxide in water?
What is the solubility product of calcium hydroxide in water? The solubility product is the concentration of the ions of a compound in a saturated solution. In a saturated aqueous solution, the dissociation of calcium hydroxide is as follows:
What is the equilibrium constant of Kp?
For example, the equilibrium constant for the oxidation of sulfur dioxide to sulfur trioxide is 4.0 × 10 24 atm −1 at 298K, 2.5 × 10 10 atm −1 at 500K, and 3.4 atm −1 at 1000K. (Of course, Kp can be determined from Kc using the ideal gas law.)
What is the ratio of effective concentration to actual concentration?
The ratio of effective concentration to the actual concentration is known as the activity coefficient of the ion. Generally, as the total ionic strength of a solution increases, the activity coefficient of a given species decreases from unity. The activity is the effective concentration of ionic species.
Why is KSP called the solubility product?
Ksp is called the solubility product because it is literally the product of the solubilities of the ions in moles per liter. The solubility product of a salt can therefore be calculated from its solubility, or vice versa. Photographic films are based on the sensitivity of AgBr to light.
When is the equilibrium of the salt at equilibrium?
When it is equal to the solubility product for the salt , the system is at equilibrium. The reaction eventually comes back to equilibrium after the excess ions precipitate from solution as solid AgCl. When equilibrium is reestablished, however, the concentrations of the Ag + and Cl - ions won't be the same.
What happens when AgBR crystals do not absorb light?
AgBr crystals that do not absorb light are then removed from the film to "fix" the image. Example: Let's calculate the solubility of AgBr in water in grams per liter, to see whether AgBr can be removed by simply washing the film. We start with the balanced equation for the equilibrium.
Is AgCl a constant?
Since the [AgCl] term is a constant, which has no effect on the equilibrium, it is built into the equilibrium constant for the reaction.
Is silver nitrate soluble in water?
Imagine what happens when a few crystals of solid AgNO 3 are added to this saturated solution of AgCl in water. According to the solubility rules, silver nitrate is a soluble salt. It therefore dissolves and dissociates into Ag + and NO 3- ions. As a result, there are two sources of the Ag + ion in this solution.
Problem

Solution
The key to solving solubility problems is to properly set up your dissociation reactions and define solubility.

The solubility product of AgCl is 1.6 x 10 -10. The solubility product of BaF 2 is 2 x 10 -6 .
Ksp to mass
We can determine how many grams of a substance is present in a saturated solution from the Ksp. Suppose we want to know how much AgCl (by mass) is dissolved in a 10.0 L saturated aqueous solution. The Ksp for AgCl is 1.77 × 10 –10.
Solutions with a common ion
We can reexamine the mass of a solute in an aqueous solution containing a common ion. Suppose we want to know how much AgCl (by mass) can be dissolved in a 10.0 L 0.100 M NaCl aqueous solution. The Ksp for AgCl is 1.77 × 10 –10 . Note that the solution contains a common ion (Cl –) with AgCl.

How are solubility products defined?

What is the equilibrium constant?
The equilibrium constant is called the solubility product , and is given the symbol Ksp. To avoid confusing clutter, solubility product expressions are often written without the state symbols. Even if you don't write them, you must be aware that the symbols for the ions that you write are for those in solution in water.
What happens when you mix barium and sulphate?
If you mix together two solutions containing barium ions and sulphate ions and the product of the concentrations would exceed the solubility product, you get a precipitate formed. Enough solid is produced to reduce the concentrations of the barium and sulphate ions down to a value which the solubility product allows.
Is barium sulphate soluble in water?
It isn't totallyinsoluble - very, very small amounts do dissolve. That's true of any so-called "insoluble" ionic compound. if you shook some solid barium sulphate with water, a tiny proportion of the barium ions and sulphate ions would break away from the surface of the solid and go into solution.
Can you get a precipitate if you lower the concentration of the ions?
If you lower the concentrations of the ions enough, you won't get a precipitate - just a very, very dilute solution of barium sulphate. So it is possible to get an answer less than the solubility product when you multiply the ionic concentrations together if the solution isn't saturated.
Can you use solubility products on ionic compounds?
There's nothing new here. Solubility products only apply to sparingly soluble ionic compounds. You can't use solubility products for normally soluble compounds like sodium chloride, for example. Interactions between the ions in the solution interfere with the simple equilibrium we are talking about.
Is concentration a constant in heterogeneous equilibrium?
In a heterogeneous equilibrium, concentration terms for solids are left out of the expression. Note: The simplest explanation for this is that the concentration of a solid can be thought of as a constant. Rather than have an expression with two constants in it (the equilibrium constant and the concentration of the solid), ...
