Why we use phenopthline as indicator for determining theconcentration of oh?
Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.
Why you are adding phenolphthalein as a indicator?
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.
What is the color of phenol red at acidic pH?
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
