Question

The acid form of the indicator bromocresol green has ka = 2.0 * 10-5. For which one of the following types of titrations woul

Answer 1

Answer #1

It's color change rang at 5.3 ( pKa = 5.3 and Ka = 2.0 • 10^-5)

So we used this indicator for stronger acid vs weaker base. Because it's changed the color at lower pH

Correct answer is

First option

Answer 2
