* pH scale: The pH scale ranges from 0 to 14.
* 0-6: Acidic
* 7: Neutral
* 8-14: Basic (or alkaline)
* Strength of acids: The strength of an acid depends on how readily it donates hydrogen ions (H+) in solution.
* Strong acids completely ionize in solution, meaning they donate all their hydrogen ions.
* Weak acids only partially ionize, meaning they donate only a small fraction of their hydrogen ions.
* pH 6: A pH of 6 indicates a relatively low concentration of hydrogen ions, suggesting that the acid is not fully ionizing. This is characteristic of a weak acid.
Example: Acetic acid (found in vinegar) has a pH around 2.4, making it a weak acid.
