# What is the Molar Solubility of BaF2 in Water and NaF Solution?

• kirsten_2009
In summary, the molar solubility of barium fluoride (BaF2) in water at 25 degrees Celsius can be calculated using the solubility product constant (Ksp) of 1.0 x 10^-16. To find the molar solubility in 0.15 M NaF at 25 degrees Celsius, we can use the equation Ksp = [D][C] / [B][A] and consider the relationship between the concentrations of F- and Ba2+.

## Homework Statement

A.) Calculate the molar solubility of barium fluoride BAF2 in water at 25 degrees Celsius. The solubility product constant for BaF2 at this temperature is 1.0 x 10^-16

B.) What is the molar solubility of BaF2 in 0.15 M NaF at 25 degrees Celsius? Compare the solubility in this case with that of BaF2 in pure water.

## Homework Equations

A + B --> C + D

Ksp = [D][C] / [A]

## The Attempt at a Solution

No clue...

What is exact formula for Ksp of BaF2? How are the concentrations of F- and Ba2+ related? (hint: take a look at the compound formula).

## 1. What is solubility in chemistry?

Solubility in chemistry refers to the ability of a substance to dissolve in a solvent, such as water. It is a measure of the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.

## 2. How do you calculate solubility?

Solubility can be calculated by dividing the mass of the solute by the mass of the solvent and multiplying by 100. This gives the solubility as a percentage. Alternatively, solubility can also be calculated by plotting a solubility curve, which shows the relationship between solubility and temperature.

## 3. What factors affect solubility?

The solubility of a substance is affected by several factors, including temperature, pressure, polarity, and the chemical nature of the solute and solvent. For example, temperature generally increases the solubility of solids in liquids, whereas pressure has a greater impact on the solubility of gases in liquids.

## 4. How does solubility differ from miscibility?

Solubility refers to the ability of a substance to dissolve in a solvent, while miscibility refers to the ability of two substances to mix and form a homogeneous solution. Solubility is a measure of the maximum amount of solute that can dissolve in a given amount of solvent, while miscibility is a qualitative measure of how well two substances will mix together.

## 5. What is the difference between saturated and unsaturated solutions?

A saturated solution is one in which the maximum amount of solute has been dissolved in a given amount of solvent at a specific temperature and pressure. An unsaturated solution is one in which more solute can still be dissolved. This can be achieved by either increasing the temperature or decreasing the amount of solvent in the solution.
