Acids, bases, and salts are three fundamental types of chemical compounds. Understanding their properties and how they interact is crucial in chemistry.

Redox is short for reduction-oxidation. These two processes always happen together.
* Oxidation is the loss of electrons (LEO – Loss of Electrons is Oxidation).
* Reduction is the gain of electrons (GER – Gain of Electrons is Reduction).

The substance that gets oxidized is the reducing agent because it causes another substance to be reduced.

When we talk about the rate of reaction, we're measuring how quickly the concentration of reactants decreases or the concentration of products increases over time. It's essentially the speed of a chemical process.

Organic chemistry focuses on molecules containing carbon. Carbon's special ability to form four strong covalent bonds, especially with other carbon atoms, leads to the vast diversity of organic compounds.
