Do bases turn phenolphthalein clear?
No, bases turn phenolphthalein pink or purple in color. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions with a pH higher than around 8.2.
When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?
It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.
The true equivalence point in these titration was at pH7 What is the pH range for the color change of phenolphthalein?
Phenolphthalein changes color in the pH range of approximately 8.2 to 10.0. This means that phenolphthalein starts to turn pink around pH 8.2 and turns completely pink at around pH 10.0. Since the equivalence point was at pH 7, phenolphthalein would not be the ideal indicator for this titration.
What colour would phenolphthalein turn in alkin?
Phenolphthalein is a pH indicator that turns pink in basic solutions. In the presence of an alkyne, which is typically non-basic, phenolphthalein would remain colorless if the alkyne is not deprotonated to form a basic solution. However, if the alkyne is reacted with a strong base, it could lead to a color change to pink due to the formation of an enolate ion or a similar basic species.
How do you turn water into wine using phenolphthalein?
Phenolphthalein is a pH indicator and cannot be used to turn water into wine. Wine is made through the process of fermentation using grapes or other fruits, yeast, and time. Phenolphthalein changes color in response to a change in pH, typically from colorless to pink or red in the presence of a base.
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.
Will acids turn phenolphthalene indicator pink?
No, phenolphthalein turns colourless when it comes into contact with an acid. It only turns magenta with a base (alkali)
Do bases turn phenolphthalein pink?
Yes, bases turn phenolphthalein pink because phenolphthalein is colorless in acidic solutions but turns pink in basic solutions with a pH around 8.2 to 10.
Will phenolphthalein turn pink in coca-cola?
No, Coke would have to have a PH of more than 10 to turn pink. Coke only has a PH of 3
Do bases turn phenolphthalein clear?
No, bases turn phenolphthalein pink or purple in color. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions with a pH higher than around 8.2.
What causes phenolphthalein to turn pink?
Phenolphthalein turns pink when it comes into contact with a basic solution, due to a chemical reaction that changes its molecular structure.
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
What color does ammonia turn when phenolphthalein is added?
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
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 you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
