What color does NaoH turn when phenolphthalein?
NaOH turns pink when phenolphthalein is added.
What is the color change of phenolphthalein in a basic solution?
Phenolphthalein turns pink in a basic solution.
What is the color of lime water when phenolphthalein is added into lime water?
The color is pink with phenolphthalein.
What color change does phenolphthalein undergo in a basic solution?
Phenolphthalein turns pink in a basic solution.
Is phenolphthalein a chemical property or a physical property?
Phenolphthalein itself is a chemical. It changing color is a chemical change.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
What color indicates that a titration using phenolphthalein has reached the end point?
The color pink indicates that a titration using phenolphthalein has reached the end point.
What happens if phenolphthalein was added to salts?
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.
What will be the color of phenolphthalein when added to a solution of hydroxide?
Phenolphthalein will turn pink or magenta in color when added to a basic solution containing hydroxide ions.
What happens when water is added to phenolphthalein?
When water is added to phenolphthalein, the color remains the same, which is colorless. Phenolphthalein is typically used as an indicator in titrations with strong acid and strong base where the color change is triggered by changes in pH, not by the addition of water.
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.
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.
