What color change does phenolphthalein undergo in a basic solution?
Phenolphthalein turns pink in a basic solution.
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 is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
What happens if phenolphthalein solution is added in hydrochloric acid?
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
What color change the occur when phenolphthalein is put into the base?
Phenolphthalein changes from colorless to pink in a basic solution. This color change occurs because phenolphthalein is a pH indicator that is clear in acidic solutions and pink in basic solutions with a pH above 8.2.
What color change does phenolphthalein undergo in a basic solution?
Phenolphthalein turns pink in a basic solution.
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.
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 is the color when caustic soda reacts with phenolphthalein?
When caustic soda (sodium hydroxide) reacts with phenolphthalein, the solution turns pink or magenta in color. This color change indicates that the solution has become basic or alkaline.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
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.
How will Phenolphthalein help you test for unknown substances?
Phenolphthalein is a pH indicator that changes color in response to different pH levels. By using phenolphthalein, you can determine if a solution is acidic or basic based on the color change it exhibits. This can help you identify unknown substances by comparing the color change with known pH values of different substances.
What happens if phenolphthalein solution is added in hydrochloric acid?
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
What happens when you mix calcium hydroxide and phenolphthalein?
When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
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 color change the occur when phenolphthalein is put into the base?
Phenolphthalein changes from colorless to pink in a basic solution. This color change occurs because phenolphthalein is a pH indicator that is clear in acidic solutions and pink in basic solutions with a pH above 8.2.
What happens with phenothalein is placed in Magnesium hydroxide?
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
