What is indicator which has no color with the acidic medium?
Phenolphthalein and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.
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 an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.

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 does battery acid go in universal indicators?
Battery acid typically turns red in universal indicators, indicating that it is acidic.
What colour is phenolphthalein when soda is added?
As soda contains carbon dioxide, it's actually a dilute solution of carbonic acid, hence phenolphthalein remains colourless.
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?
Washing soda is sodium carbonate and phenolphthalein will be pink in colour in a solution of washing soda.
