Question

The following acid-base indicators are available to follow the titration. Which of them would be most appropriate for signaling the endpoint of the titration? EXPLAIN

------- COLOR CHANGE ------ INDICATOR <-> Acid form <-> Base Form <-> pH Transition Interval
Bromphenol blue <-> yellow <-> blue <-> 3.0-5.0 Bromthymol blue <->yellow <-> blue <-> 6.0-7.6 Thymol blue <-> yellow <-> blue <-> 8.0-9.6 PLEASE ANSWER IT!!!!!!!!!!!!!!!

Answer 1

Bromthymol blue <->yellow <-> blue <-> 6.0-7.6
is the most suitable indicator for titration since the pH transition interval occurs in a range between acidic pH and basic pH
Titration is done to determine how much acid or base is present in a solution and the indicator should be able to signal the point when the acid or base has completely reacted
