Question

suggest a method that is generally used for measuring the pH value

Answer 1

A pH metre is the most accurate method used for measuring the pH value.

Answer 2

Answer:

The common method that is generally used for measuring the pH value is calorimetry.

Explanation:

Calorimetry is the method where the values of given solutions are measured by colour change.

The test solution is mixed with some chemicals which react with the solution and bring change in the colour of the solution.

Thus changed colour indicates the pH value of the solution.

Litmus paper test is also another type of test used to know the pH of the solution.
