What Is a Basic Solution in Chemistry?

A basic solution is a liquid mixture that has a pH level greater than 7, which typically means there are a greater number of hydroxide ions than hydrogen ions. Basic solutions are typically formed by mixing a base, like sodium hydroxide and water.

The strength of a basic solution, indicated by how far above the pH level of the solution is above 7, is determined by the strength of the base used. A strong base will almost fully dissociate into its component ions, leading to a higher concentration of hydroxide ions. Basic solutions can be formed by mixing a high amount of a base with a small amount of an acid.
