Some Basic Concepts of Chemistry

In this introductory topic, we will study the definition of chemistry and its importance. We will understand the important roles of chemistry in our daily life.

This topic explains the classification of matter based on their physical and chemical properties. It discusses the nature of matter via examples.

The topic discusses the physical and chemical properties of matter. It highlights the ancient methods of measurement including English system and the metric system.

The topic describes the main five laws of chemical combination. It covers law of conservation of mass, definite proportions, multiple proportions, Gay Lussac's law of gaseous volumes and Avogadro's Law.

The topic discusses the Dalton's Atomic Theory. It mentions the propositions given by Dalton along with some drawbacks of this theory.

A brief explanation of the atoms and molecules is provided in this topic. It covers the definitions given by Avogadro. These descriptions help in differentiating between an atom and a molecule.

This topic explains the concept of atomic mass and molecular mass. It describes the formula mass as well as average atomic mass. It also explains unified mass, atomic mass unit and isotopes with examples.

This topic discusses the atomic and isotopic masses. It explains different terms associated with atomic mass. We will learn about formula mass and average atomic mass. It also covers some examples related to atomic masses.

In this topic, we will know the definition of a mole. It gives the example of a mole of carbon, water and oxygen. We will also learn about Avogadro constant, mole of atoms and molecules, and mole concept.

In this topic, we will study the concept of the empirical and molecular formula. We will learn the steps to determine the empirical and molecular formula of an element. We will also learn to calculate the mass percentage of an element.

The topic explains the concept of a balanced chemical equation. We will learn how to balance a chemical equation in this topic. It covers limiting reagent and reactions in solutions. It consists of problems with solutions.

In this topic, we will learn how to determine the relative molecular or atomic masses. We will also learn the differences between the relative formula and relative molecular masses.

This topic explains the concept of chemical equivalents through definitions. It explains the equivalent weight and its calculation using different methods. It also describes the procedure of each method with examples.

This topic explains the volumetric calculations in detail. It gives the definitions of primary and secondary standard solutions along with examples. It also describes the concentration of solutions and terms used in volumetric calculations.
