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 indicator has no color at all?
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
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.
Which indicator gives us reddish pink color in acidic solution?
The red or pink color in an acidic solution is typically due to the presence of an acid-base indicator called phenolphthalein. In acidic conditions, phenolphthalein turns colorless, while in basic conditions it turns red or pink.
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 is phenolphthalein?
it is a agar medium for Microbiology containing phenolphthalein biphosphate. It is used in Petri plates and detects the phosphatase character of microbial colonies but requires final addition of alkali to color the phenolphatlein and the color rapidly fades.
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.

What color would tap water turn with phenolphthalein?
Generally tap water is acidic. There is no color changes.
How do you determine if a substance is an acid or a base using phenolphtalein indicator?
Phenolphthalein is colorless in acidic solutions and pink in basic solutions. By adding phenolphthalein to a substance, you can observe the color change to determine if the substance is acidic or basic based on the change in color.
What is the colour change of carrot indicator in acid medium?
Carrot indicator turns yellow in an acidic medium. This change in color is due to the presence of anthocyanins that react with the acidic solution.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Phenolphthalein change color when mixed with hydrochloric acid?
Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.
