Known Applications:

chemical indicator for weak acids and bases; observing photosynthetic activities or respiratory indicators (turns green then yellow as CO2 is added); weak acid in solution. It can thus be in protonated or deprotonated form, appearing yellow and blue respectively; bluish green in neutral solution; laboratory biological slide stain to define cell walls or nuclei under the microscope; measuring substances that would have relatively low acidic or basic levels (near a neutral pH); managing pH of pools and fish tanks, and measuring the presence of carbonic acid in a liquid; used in obstetrics for detecting premature rupture of membranes
