In summary, solubility is the ability of a substance to dissolve in another substance to form a homogeneous mixture. It is typically measured in terms of the amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure. The solubility of a substance can be affected by factors such as temperature, pressure, and the nature of the solute and solvent. Concentration, which refers to the amount of solute present in a given amount of solvent, is closely related to solubility. Solubility affects the maximum concentration of a solution, but other factors such as temperature and pressure can also influence concentration.

Homework Statement


Lithium phosphate, Li3PO4, has a solubility product Ksp = 2.37 × 10-4. What is the concentration of Li+ ions in a saturated solution of Li3PO4?

The Attempt at a Solution



What is the initial concentration of Lithium? Or does it matter?

I got 0.163 M but answer says 0.0544 M

Without it I can't do it! Somebody please help. Thanks.

0.163 M looks OK to me, 0.0544 is three times too low (which suggests an obvious mistake).

Ok thanks for confirming.
 

Related to How to Calculate Li+ Ion Concentration in Saturated Li3PO4 Solution?

1. What is solubility?

Solubility is the ability of a substance, known as the solute, to dissolve in another substance, known as the solvent, to form a homogeneous mixture.

2. How is solubility measured?

Solubility is typically measured in terms of the amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure. The most common unit of measurement is grams of solute per 100 milliliters of solvent (g/100mL).

3. What factors affect solubility?

The solubility of a substance can be affected by several factors, including temperature, pressure, and the nature of the solute and solvent. Generally, as temperature increases, solubility also increases. Pressure has a more significant effect on the solubility of gases than liquids. Additionally, the polarity and molecular structure of the solute and solvent can play a role in solubility.

4. What is concentration?

Concentration refers to the amount of solute present in a given amount of solvent. It can be measured in various units, such as molarity (moles of solute per liter of solution), molality (moles of solute per kilogram of solvent), or percent concentration (% w/w or % w/v).

5. How is concentration related to solubility?

Concentration and solubility are closely related, with solubility affecting the maximum concentration of a solution. For example, if a solute has a low solubility, it will only dissolve in a small amount of solvent, resulting in a low concentration. On the other hand, a highly soluble solute can form a concentrated solution with a larger amount of solvent. However, other factors, such as temperature and pressure, can also influence the concentration of a solution.
