Definitions:

Strong Base

A strong base is a substance that can completely dissociate into its ions in aqueous solution, resulting in a high pH.

Weak Base

A base that does not fully dissociate in solution, resulting in a relatively low pH compared to strong bases.

pH

A scale used to specify the acidity or basicity of an aqueous solution, with values ranging from 0 (very acidic) to 14 (very basic), and 7 being neutral.

pH

A numerical scale ranging from 0 to 14 that determines the level of acidity or alkalinity in water-based solutions.
