Homework Answers
Methyl orange - Red (Below pH 3.4) to yellow (Above pH4.4) via orange color
Crystal Violate-Yellow (Below pH -1.0) to violate (Above pH 2.0)
Bromothymol blue- Yellow (Below pH 6.0) to Blue (Above pH 7.6)
Phenolphthalein - Orange (Below pH 0) to colorless (Between pH 0-8.2) Pink (Between pH 8.2-10.0) again colorless above pH 10.0
Bromocresosl -Yellow (Below pH 3.8) to Blue (Above pH 5.4)
Allizarin Yellow- Yellow (Below pH 10.1) to Red (Above pH 12.0)
Hence the answer is 3.8-4.0
