Study Notes

Solutions and Mixtures

Mixtures consist of two or more substances that are not chemically combined.
When sugar dissolves in water, it forms a solution, demonstrating the process of dissolution.
Solutions can be categorized based on their states; for example, gas in liquid is a common type.

Types of Mixtures

A homogeneous mixture has uniform composition, meaning the individual components are indistinguishable.
A heterogeneous mixture contains distinct phases or components that are identifiable and do not blend uniformly.
Foods like biko, nilupak, and buko salad exemplify heterogeneous mixtures due to their visible and separate components.

Characteristics of Mixtures

The definition of a mixture highlights that it does not create new substances, maintaining the original chemical properties of its components.
In solutions like sugar in water, components retain their properties even when physically combined, as evidenced by the sweet taste of the solution.

Components of Solutions

In a solution, the substance that gets dissolved is known as the solute, while the substance doing the dissolving is referred to as the solvent.
An example of a solution is a sugar solution, where sugar acts as the solute and water as the solvent.

Classification of Solutions

Gas in gas mixtures, like air, or liquid in liquid mixtures, such as cola or soft drinks, fall under different categories of solutions based on their components’ states.
The term ‘solution’ is often used synonymously with homogeneous mixtures due to their indistinguishable nature after mixing.

Solubility

Defined as the ability of a solute to dissolve in a solvent at a specific temperature.
Influenced by factors like temperature, nature of solute, and solvent quantity.

Miscibility

Describes a substance's ability to mix evenly and completely with another substance.
It impacts the solubility of substances.

Factors Affecting Solubility

Higher temperatures speed up the dissolution of solutes.
The nature of the solute and the solvent influences dissolving efficiency.
Particle size affects solubility; smaller particles dissolve faster.
Stirring plays a significant role in the dissolving process.

Nail Polish and Acetone

The effectiveness of nail polish removal with acetone relates to miscibility and the nature of both substances.
Factors such as particle size and temperature may also play a role.

Behavior of Solute in Water

When mixed with water, solute particles form a mixture.
In a suspension, solute particles may not dissolve fully and can settle out.

Characteristics of Suspensions

Suspensions are heterogeneous mixtures where particles eventually settle out after mixing.
Examples include mixtures that do not completely dissolve, leading to sedimentation.

Mixture Types

A suspension is categorized as a heterogeneous mixture.
Contrasts with homogenous mixtures where components are evenly distributed.

Identifying Suspensions

Particles that do not dissolve and settle can indicate a suspension.
Not all mixtures with undissolved particles are classified as suspensions; complete dissolution defines homogenous mixtures.

Example of Suspensions

Mixtures such as flour in water, and oil in water are classified as suspensions due to undissolved particles.
Water and sugar typically do not create a suspension; they form a solution.
