What is the range of the pH scale?

1-10
0-12
0-14
1-14

The correct answer is: 0-14

The pH scale is a measure of the acidity or basicity of a substance, and it ranges from 0 to 14. A substance with a pH of 7 is considered neutral, with anything below 7 being acidic and anything above 7 being basic. Option A is incorrect because it only covers a portion of the pH scale, excluding the highly acidic and basic ends. Option B is also incorrect because the pH scale does not extend past 14. Option D is incorrect because it excludes the possibility of a substance having a pH of 0, which is extremely acidic. Therefore, option C is the correct answer as it encompasses the full range of the pH scale.
