# Frequent question: What is solubility constant Ksp?

Contents

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 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 KSP?

Ksp is called solubility product constant, or simply solubility product. In general, the solubility product of a compound represents the product of molar concentrations of ions raised to the power of their respective stoichiometric coefficients in the equilibrium reaction.

## How do you find the solubility constant?

To do this, simply use the concentration of the common ion as the initial concentration. Example: Estimate the solubility of barium sulfate in a 0.020 M sodium sulfate solution. The solubility product constant for barium sulfate is 1.1 x 1010.

## What does KSP 1 mean?

Solubility product constant is simplified equilibrium constant (Ksp) defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates in water. The higher the solubility product constant, the more soluble the compound.

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 KSP affected by?

The solubility product is a kind of equilibrium constant and its value depends on temperature. Ksp usually increases with an increase in temperature due to increased solubility.

## What is the solubility of AgCl?

The solubility of AgCl is 1.3 x 105 mol/L at 25oC.

## What is solubility unit?

Water solubility is a measure of the amount of chemical substance that can dissolve in water at a specific temperature. The unit of solubility is generally in mg/L (milligrams per liter) or ppm (parts per million). You can often find it in the section 9 of a safety data sheet (SDS).
