Chemistry: Solutions and Alloys Quiz

Study Notes

Dissolution and Solution Formation

Solute: A substance that dissolves in another substance. The amount of solute affects the concentration of the solution.
Dissolution: The process of dissolving substances.
Soluble: A substance that dissolves in a solvent.
Insoluble: A substance that does not dissolve in a solvent.
Miscible: Substances that mix in any amount (e.g., alcohol and water).
Immiscible: Substances that do not mix (e.g., oil and water).

Solid Solutions - Alloys

Alloys: Solutions of metals mixed with another element.
- Steel: iron (metal) + carbon (non-metal)
- Bronze: copper (metal) + tin (metal)
- Brass: copper (metal) + zinc (metal)

Liquid Solutions

Liquid Solutions: Mixtures of two or more substances forming a solution.
- Vinegar: Acetic acid + water.
- Dextrose solution: Sugar + water
- Calamansi juice example: A 16g sample of calamansi juice mixed with 85g of water results in a 15.84% concentration by mass.

Concentration Calculations

Concentration: The amount of solute in a given amount of solvent.
Concentration calculations can involve various measurement methods.
The text provides an example of percentage by mass calculation for Calamansi juice, a specific type of liquid solution.
The text also provides a general example of concentration calculation involving a solute, solvent, and additional solute added to the solution.

Gaseous Solutions

Air is a gaseous solution, a homogeneous mixture of gases.
The primary components of air include nitrogen (78%), oxygen (20.9%), and other gases (0.17%).
Argon makes up 0.90% of air, while carbon dioxide accounts for 0.03%.
Dry air in the atmosphere is composed of predominantly nitrogen, oxygen, and carbon dioxide.

Liquified Petroleum Gas (LPG)

LPG is a liquid at atmospheric pressure.
When subjected to heat or pressure, it becomes a gas, such as when used for burning on a stove.
LPG primarily consists of propane and butane.

Types of Solutions Based on Solute Amount

Saturation refers to the maximum amount of solute that can dissolve in a given solvent.
Unsaturated solutions contain less solute than the maximum solubility.
Saturated solutions contain the maximum amount of solute that can dissolve at a given temperature and pressure.
Supersaturated solutions contain more solute than the maximum solubility. These solutions are unstable and require additional solvent or heat to dissolve the excess solute.

Factors Affecting Solubility

Solubility refers to the ability of a solute to dissolve in a given solvent.
Solubility is influenced by factors such as temperature and pressure.
The solubility of solids usually increases with higher temperatures.
The solubility of gases in water decreases with higher temperatures.
