How do you prepare 1 percent phenolphthalein in 2000ml?
To prepare a 1% phenolphthalein solution in 2000mL, you would need to dissolve 20g of phenolphthalein in 2000mL of solvent (usually water or alcohol). This will result in a 1% solution by weight/volume. Remember to wear appropriate personal protective equipment and handle chemicals with care.
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 colour in sulfuric acid is phenolphthalein?
Phenolphthalein is colorless in sulfuric acid.
Is phenolphthalein a compound?
Yes, phenolphthalein is a compound with the molecular formula C20H14O4.
Which Colour do alkali turn phenolphthalein?
Alkalis turn phenolphthalein pink or magenta.
Does Ammonia turns phenolphthalein in to pink?
No, ammonia does not turn phenolphthalein pink. Phenolphthalein is a pH indicator that turns pink in basic solutions, but ammonia is a weak base and typically does not have a strong enough pH to turn phenolphthalein pink.

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.
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 would happen if I placed a Vial of phenolphthalein into a jar with ammonia?
Nothing will happen... but when you put a drop of the vial in the phenolphthalein, the phenolphthalein will turn into pink... It was just an observation that I saw in our experiment this afternoon
