What does the pH scale range from?
A
0-10
B
2-15
C
1-5
D
0-14
Explanation: 

Detailed explanation-1: -pH is a measure of how acidic/basic water is. The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Detailed explanation-2: -The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic).

Detailed explanation-3: -The pH of a solution varies from 0 to 14. Solutions having a value of pH ranging from 0 to 7 on the pH scale are termed as acidic and the value of pH ranging from 7 to 14 on pH scale are known as basic solutions. Solutions having the value of pH equal to 7 on pH scale are known as neutral solutions.

Detailed explanation-4: -This is because, in order to reach pH levels below 0 or above 14, one would require extraordinarily acidic or basic solutions, respectively. A saturated sodium hydroxide solution (NaOH) solution is supposed to have a pH of 15 based on its molarity.

Detailed explanation-5: -Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. pH scale, ranging from 0 (very acidic) to 14 (very basic/alkaline) and listing the pH values of common substances.
