Study Notes
Objectives of Inorganic Chemistry
- Defines and differentiates from other chemistry subjects.
- Recalls basic concepts essential for understanding chemistry.
- Discusses the importance of inorganic chemistry in the pharmaceutical industry.
Definition of Chemistry
- Chemistry is the study of characteristics, composition, and transformations of matter.
Definition of Inorganic Chemistry
- Focuses on the study of inorganic compounds and materials, distinct from organic chemistry.
Basic Concepts of Matter
- Matter: Anything with mass that occupies space.
- Mass: Quantity of matter in an object, measured using a balance.
- Volume: Space an object occupies, assessed with a ruler or graduated cylinder.
Properties of Matter
- Physical Properties: Characteristics that describe matter, such as color, smell, size, temperature, shape, state, and texture.
- Chemical Properties: Describe how a substance undergoes change to form new substances (e.g., copper turning green when oxidized).
Characteristic Properties
- Properties that remain constant regardless of mass or volume, defining the substance itself.
- Examples include boiling point, hardness, melting point, pH, solubility, flammability, conductivity, and density.
Types and States of Matter
- States of Matter: Solid, liquid, gas, and plasma.
- Solid: Defined shape and volume, tightly packed particles.
- Liquid: Defined volume, no defined shape, loosely packed particles.
- Gas: No defined shape or volume, particles far apart and moving freely.
- Plasma: Ionized gas, conducts electricity well and is influenced by magnetic fields.
Changes in Matter
- Physical Changes: Alter physical properties without changing the chemical identity (e.g., boiling water, dissolving sugar).
- Chemical Changes: Alter substances to form new substances (e.g., burning, rusting). Indicated by odor changes, fizzing, temperature shifts, color changes, or precipitate formation.
Law of Conservation of Mass
- Established by Antoine Lavoisier, stating that mass is neither created nor destroyed in ordinary chemical and physical changes, only transformed.
