What is indicator which has no color with the acidic medium?
Litmus paper is an indicator that has no color in an acidic medium. It turns red in acidic solutions and blue in basic solutions.
What is the colour of phenolphthalein after addition of dilute HCl?
The color of phenolphthalein after the addition of dilute HCl is colorless. Phenolphthalein is typically pink in basic solutions but turns colorless in acidic conditions due to the change in pH.
What is the colour of phenolphthalein in tap water?
Phenolphthalein is colorless in tap water, as tap water is typically neutral to slightly acidic. It only turns pink in basic solutions with a pH above 8.2.
When phenolphthalein is added to ammonium hydroxide is the color of the final solution is pink?
Phenolphthalein is a colorless indicator in acidic solutions but turns pink in basic solutions. If phenolphthalein turns pink when added to ammonium hydroxide, which is a basic solution, it indicates the presence of a pH above 7.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein is colorless in acidic solutions and turns pink or red in basic solutions.

What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein is colorless in acidic solutions and turns pink or red in basic solutions.
What colour does battery acid go in universal indicators?
Battery acid typically turns red in universal indicators, indicating that it is acidic.
What does phenolphthalein mean in science?
Phenolphthalein is a chemical compound with the formula C20H14O4. It is coloured, and the colour changes in relation to the acidity of it environment. It turns colorless in acidic solutions and pink in basic solutions.
What colour is phenolphthalein when soda is added?
Phenolphthalein is colorless in the presence of acidic solutions, but turns pink in the presence of basic solutions, such as soda.
How do pH indicator dyes show a change in pH from acidic to basic or vice versa?
Certain indicators only change colour when placed in a particular pH level or range (e.g. litmus) and others are colourless in certain conditions (e.g. phenolphthalein, leuchomalachite green's second transition).
Why phenolphthalein get colour on basic medium?
Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.
What colour in sulfuric acid is phenolphthalein?
Phenolphthalein is colorless in sulfuric acid.
What is the color of phenolphethaline in washing soda?
Phenolphthalein is colorless in acidic solutions and pink or magenta in alkaline solutions. In washing soda (sodium carbonate), which is alkaline, phenolphthalein would appear pink or magenta.
