Q: The strength of bases is measured on what scale?


Read this paragraph and choose the correct option from the provided answers:

The strength of bases is measured on a scale called the pH scale, which ranges from 0 to 14. On this scale, a pH value of 7 indicates a neutral solution, and a pH value greater than 7 indicates a basic solution. The higher the pH value is, the stronger the base. The strongest bases, such as drain cleaner, have a pH value close to 14.

 Choices:

- acid test

- litmus test

- pneumatic scale

- ph scale


A:
ph scale
