pH

A scale used to specify the acidity or basicity of an aqueous solution, ranging from 0 (acidic) to 14 (basic).

Buffer Solution

A solution that can resist changes in pH when small quantities of an acid or base are added, maintaining a relatively constant pH.

pH

A measurement system that identifies whether an aqueous solution is acidic or alkaline, with values extending from 0 (indicative of acidity) to 14 (signifying basicity).
