Definitions:

Base

In chemistry, a base is a substance that can accept protons (H+) from acids or donate a pair of valence electrons to form a bond, and it often has a high pH when dissolved in water.

Dissociates

Refers to the process by which molecules or ionic compounds split into smaller particles, often ions, in solution.

Rainwater

Water precipitated from clouds in the form of rain, often considered as a natural source of relatively clean water.

Acidic

A description for substances with a pH less than 7, indicating a higher concentration of hydrogen ions (H+) than water.
