Acids are found on the lower end of the pH scale, typically with values below 7.

Here's a breakdown:

* pH scale: Ranges from 0 to 14.

* Acids: Have a pH less than 7.

* Neutral: pH of 7 (like pure water).

* Bases (alkalines): Have a pH greater than 7.

The further down the scale you go (closer to 0), the stronger the acid.
