chemical reaction, we have a new definition of acidity and basicity, called "Lewis acidity/basicity." ALewis baseis a compound that donates an electron pair to another compound (the ammonia in our example). ALewis acidis a compound that accepts an electron pair (the H+ion in our example)...
Brønsted-Lowry or Brønsted theory explainsacid-basereactions as an acid releasing the proton and a base accepting the proton. While the acid definition is somewhat the same as that, which was proposed by Arrhenius (hydrogen ion is a proton), the definition of what constitutes a base is m...
In chemistry, we have 3 theories that define acids. The first theory developed was the Arrhenius theory, which states that an acid is a chemical that... Learn more about this topic: Lewis Acid & Base | Definition & Examples from
The Arrhenius definitions are correct in that they identify the hydroxide ion as the active component for bases. For acids, the Arrhenius definitions specify that the acid substance dissolves to form positive hydrogen H+ions, the corresponding active component for acids. These definitions may apply t...

Acids and bases are measured on the pH scale. A neutral solution has a pH of exactly seven, while an acid is a solution with a pH lower than seven. Bases have a pH higher than seven. Acids and bases are quite different, but they share some similarities....
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...

In chemistry, there are seven "strong" acids. What makes them "strong" is the fact that they completely dissociate into their ions (H+and an anion) when they are mixed with water. Every other acid is a weak acid. Because there are only seven common strong acids, it is easy to commit...
