Study Notes

The text is about a discussion surrounding various types and properties of solutions or mixtures.
Solid solutions exist in a solid state, such as gold alloys.
Solutions can be classified according to their composition and the amount of solute they contain.
A 10% solution contains 1 part solute to 9 parts solvent.
Inverted solutions, like sugar in water, have a greater amount of solute than solvent.
Solvent is the substance that dissolves another substance (solute).
Some solutions are isotonic (equal concentration of solutes), hypotonic (lower solute concentration), or hypertonic (higher solute concentration).
Solids can be dissolved in liquids to form solutions.
Gases can also dissolve in liquids, forming gaseous solutions.
The process of dissolving is called dissolution.
The solubility of a substance depends on the temperature and pressure.
Dissolving occurs when solute particles come in contact with a solvent and form a homogeneous mixture.
Saturated solutions contain the maximum amount of solute that can be dissolved at a given temperature and pressure.
Supersaturated solutions contain more solute than what can be dissolved at a given temperature and pressure.
When a saturated solution is heated, the excess solute precipitates out of the solution.
Solution concentration can be determined by measuring the mass of solute per unit volume or mass of the solution.
Solutions can be prepared by different methods, such as dissolving a solid in a liquid or mixing two liquids.
The pressure exerted by a solution is equal to the vapor pressure of the solvent at the solution temperature.
The solubility of a gas in a liquid increases with temperature and pressure.
Some substances form solutions with water easily, while others are insoluble.
Solutions can have different physical and chemical properties compared to their pure components.
The texture, taste, and odor of a solution can change when a solute is added.
Solutions can be used in various applications, such as industrial processes, food and beverage production, and medical treatments.

Precipitates can be collected by filtration or centrifugation.
Crystallization occurs when a saturated solution cools or the solvent is removed.
Impurities can affect the crystallization process and the purity of the crystals.
Crystals can have different shapes and sizes, depending on the cooling rate and process conditions.
The process of separating a solute from a solution is called extraction.
Extraction can be achieved by using a solvent that selectively dissolves the solute.
The process of distillation can be used to separate mixtures based on their different volatilities.
Distillation involves heating a mixture to produce a vapor, which is then cooled and condensed to form a separate liquid.

In a solution labeled as "imperial gallon-moles" with a density of 1.2 meters, the solubility of barium sulfate is being measured, which is taken as it is, meaning that the amount of solution taken is equal to the amount of solvent.
Since the solvent is "imperial gallon-moles", the weight of the barium sulfate that will dissolve in it is calculated, which is 90 % of the total mass of the solution, as it is a good density.
An important point is that the European Union requires all solution labels to indicate both the material's mass and its density, which is important for accurate calculations.
