What are four characteristics of the pH scale?

Answer 1

1.scale

2.base

3.acid

4.solution

Answer 2

1. The pH scale measures the acidity or basicity of a solution on a scale of 0 to 14.
2. A pH of 7 is considered neutral, with lower values indicating acidity and higher values indicating basicity.
3. Each unit change in pH represents a tenfold change in the concentration of hydrogen ions in the solution.
4. The pH scale is logarithmic, meaning a difference of one unit corresponds to a tenfold difference in hydrogen ion concentration.
