Answer:
Option(a) i.e" pH" is the correct answer to the given question .
Step-by-step explanation:
The main objective of pH value is to determining whether the solution is the acidic or the basic solution.The pH is determining the solution whether it is basic or acidic with the help of there pH value .The range of the pH value is from 0 to 14 with the following parameter it determines whether the solution is basic ,acidic or the neutral solution .
- If pH value is 7 then it is neutral solution .
- If pH value is greater then 7 then the solution is then it is basic solution .
- If the pH value is less then 7 then the solution is the Acidic solution .
All the other option are not determining that whether the solution is acidic or the basic solution that's why these are incorrect option .
