Which of these is true about a pH meter?
2 answers:
Answer: Option (D) is the correct answer.
Explanation:
An electronic device which is used to measure hydrogen ion activity is known as a pH meter.
That is, a pH meter is useful in detecting or knowing the acidity (due to ions) or alkalinity (due to
ions) of a solution.
Thus, we can conclude that out of the given options it is true about a pH meter that it can be used in any acid-base titration.
