Chemical Compounds and Equations
A chemical reaction involves the breaking of bonds in reactants and forming of new bonds in products.
Acids, Bases, pH and Salts
Acids and bases are two fundamental classes of chemical compounds. An acid is a substance that releases hydrogen ions (H⁺) when dissolved in water — examples include hydrochloric acid (HCl) and citric acid in lemons.
Hydrocarbons and Organic Compounds
Organic chemistry is the study of carbon-containing compounds. Carbon's ability to form four covalent bonds and bond to itself in long chains makes it uniquely suited to form the diverse molecules of life and industry.
