Description
pH
pH measures how acidic or basic a solution is, ranging from 0 to 14. A low pH (0-6) indicates an acidic solution, 7 is neutral, and a high pH (8-14) represents a basic (alkaline) solution. The pH scale is important in physical science because it influences chemical reactions, affects the properties of materials, and det...

Transcript
The pH scale determines whether a substance is acidic, basic, or neutral. It measures acidity or basicity on a scale from 0 to 14.
A pH of 7 is neutral. For example, distilled water is neither acidic nor basic.
Acids have a pH lower than 7. Stronger acids have a pH close to 0, while weaker acids have a pH around 5.
Bases have a...
