Question

why the pH value is till 14 not above 14 and why it is negative ????

Answer 1

We often label water as a neutral solution with a pH of 7. Also, any solution that seems acidic is said to have a pH of less than 7, while one that is basic is said to have a pH greater than 7. However, what are these numbers and what do they tell us about the solution? Is it true that a solution can only have pH values in the range 0f 0-14

give thanks...
