Acidity vs. Basicity: What's the Difference?

Edited by Sara Rehman || By Sawaira Riaz || Published on December 13, 2023
Acidity is the measure of a substance's ability to donate protons (H⁺ ions), while basicity is its ability to accept protons.

Key Differences

Acidity refers to the concentration of hydrogen ions (H⁺) in a solution, indicating how acidic a substance is. Basicity, in contrast, indicates the presence of hydroxide ions (OH⁻) or the ability of a substance to accept hydrogen ions.

The pH scale measures the acidity or basicity of a solution, with lower pH values indicating higher acidity and higher pH values indicating higher basicity. Both concepts are fundamental in understanding the chemical nature of substances.

Acidity often correlates with sour taste and reactivity with metals and bases, while basicity is associated with a bitter taste and slippery feel. Both properties play crucial roles in chemical reactions and biological processes.
