Acidic vs. Alkaline: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Published on November 9, 2023
Acidic substances have a pH less than 7, while alkaline substances have a pH greater than 7.
Difference Between Acidic and Alkaline
The scale used to measure the acidity or basicity (alkalinity) of a substance is called the pH scale, ranging from 0 to 14. Substances falling below the midpoint of 7 on this scale are labeled acidic. These solutions have a higher concentration of hydrogen ions (H+). Common examples of acidic substances include lemon juice and vinegar, both of which exhibit the characteristic sour taste of acids.

Alkaline, on the other hand, denotes substances with a pH exceeding 7. These are often referred to as basic. Alkaline substances have a higher concentration of hydroxide ions (OH-). Typical representatives of this group include baking soda and soap. Notably, alkaline substances may feel slippery to touch and can neutralize acidic substances.

The importance of understanding the distinction between acidic and alkaline goes beyond chemistry classrooms. For instance, our body meticulously regulates its internal pH level, ensuring it leans slightly alkaline. Deviations from this can signify health issues.

In environmental contexts, the acidity or alkalinity of water bodies can impact aquatic life. Acidic water might stem from acid rain, which can harm aquatic ecosystems. Alkaline water, in contrast, might hinder certain species' survival but can also neutralize overly acidic waters.
