Acids and Bases: Brønsted–Lowry, Arrhenius, and Lewis Models
In this video I provide an overview of acids and bases, their 3 different theories, and provide a pH chart of household items. The 3 different models or theories of acids and bases are all either a superset or subset of each other. The Lewis model is the most general and states that an acid accepts an electron pair (via a covalent bond) while a base donates an electron pair. The Brønsted–Lowry model is a subset of the Lewis model and states that an acid gives protons while a base takes protons. The Arrhenius model is a subset of the Brønsted–Lowry and states that in aqueous solutions (where water is the solvent) acids give the hydronium ion (H3O+) while bases give the hydroxide ion (OH-).
The acidity or basicity of aqueous solutions is measured on a pH scale (short for "power or potential of hydrogen") and is an inverse logarithmic chart. The higher the concentration of hydronium ions, the lower the pH and hence more acidic the solution. The lower the concentration of hydronium ions, the higher the pH and hence more basic the solution is. Note that the pH scale is logarithmic, thus and increase or decrease of 1 pH means a 10 times increase or decrease in the concentration of hydronium ions. Pure water is considered neutral and has a pH of 7. Lemon juice is acid and has about a 2 pH, whereas household bleach is very basic with a pH close to 13.
I also briefly cover surfactants, which are substances that lower the surface tension between liquids; hence are typically used as soaps or detergents.
