Introduction to Chemistry

These flashcards cover the foundational concepts of chemistry, including definitions, branches of chemistry, and laboratory safety.

What is chemistry?

The study of particles that make up matter and the changes that the particles can undergo.

Matter

Any substance that has mass and occupies space.

Five branches of chemistry

Analytical Chemistry, Physical Chemistry, Organic Chemistry, Inorganic Chemistry, and Biochemistry.

Analytical Chemistry

The branch of chemistry that investigates what substances are made of by analyzing compositions.

Physical Chemistry

The branch that studies the relationship between physics and chemistry, focusing on the physical properties of chemical systems.

Organic Chemistry

The study of compounds that contain carbon.

Inorganic Chemistry

The study of substances that do not contain carbon.

Biochemistry

The study of chemical processes in living organisms, focusing on metabolic reactions.

Importance of chemistry

Chemistry is involved in various applications including extraction of materials, water treatment, environmental protection, and cooking.

Lab safety rule: Do not eat or drink

It is essential to maintain a safe laboratory environment by not consuming food or beverages.

Mixing acids and water

When mixing acids and water, always add acid to water, not the other way around.

Boiling point

The temperature at which a substance changes from a liquid to a gas; important in fractionating mixtures.
