# Frequent question: Which is more soluble in water based on KSP?

Contents

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.

## Which Ksp is more soluble in water?

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.

## Does higher solubility mean higher Ksp?

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.

## Which one of the following is most soluble Ksp?

Higher the value of solubility product, higher is its solubility. In all these compounds the MnS is most soluble because its solubility product is maximum.

## Which is more soluble in water?

Nonpolar substances are generally more soluble in nonpolar solvents, while polar and ionic substances are generally more soluble in polar solvents.

## Is CaF2 soluble in water?

Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF2. It is a white insoluble solid.

Calcium fluoride.

## How do you determine which salt is more soluble using Ksp?

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. However, you can only directly compare salts that give equivalent numbers of ions in solution.

## Which of the following is least soluble in water Ksp?

CaF2 : Ksp = 3.9 x 10-11 (2) PbCl2: Ksp = 1.6 x 10-5 (3) AgCl : Ksp = 1.8 x 10-10 (4) Agloz: Ksp = 3.1 x 108.

## What is Ksp formula?

In general, MaXb(s) <=> aM+b(aq) + bXa(aq) is expressed as Ksp = [M+b]a[Xa]b. These expressions are called solubility product constant expressions because they involve the product of the equilibrium concentrations of the constituent ions, each raised to the power corresponding to the number of ions in the formula.

## What 4 factors affect solubility?

## 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.

## Which salt is most soluble in pure water?

Hence, Ag2CO3 has the greatest molar solubility in pure water.

## Which one of the following is most soluble Ag2CO3?

Ag2CO3 > BaF2 > Pb(OH)2 d. BaF2 > Ag2CO3 > Pb(OH)2 All salts have the same number of ions so you just compare the Ksp. The salt with the largest Ksp is most soluble.
