What is the pH if solution makes phenolphthalein stay clear?
your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
Why you are adding phenolphthalein as a indicator?
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.
What is the colour of phenolphthalein in salt water?
It will turn purple
What two clear liquids mixed make a colored liquid?
When you mix a clear solution of sodium hydroxide (NaOH) with a clear solution of phenolphthalein, the result is a colored liquid. Sodium hydroxide is a strong base, and phenolphthalein is a pH indicator that turns pink in basic conditions. When combined, the phenolphthalein changes color, resulting in a vibrant pink solution. This is a common demonstration in chemistry to illustrate acid-base indicators.
What is the name of the chemical that changes colour in acids and bases?
The chemical that changes color in acids and bases is called an indicator. Common indicators include litmus, phenolphthalein, and bromothymol blue. These substances change color in response to pH changes in a solution.
How do you turn phenolphthalein clear?
Add an acid.
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.
What color do bases turn phenolphtalein?
Phenopthalene turned into pink.pH should be above 10.
What is the pH if solution makes phenolphthalein stay clear?
your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
What colour does hydrochloric acid turn phenolphthalein?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
Which Colour do alkali turn phenolphthalein?
Alkalis turn phenolphthalein pink or magenta.
What color does phenolphthalein change in bases?
For solutions with a pH higher than 8.2, phenolphthalein turns bright 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.
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 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 color does NaoH turn when phenolphthalein?
NaOH turns pink when phenolphthalein is added.
What types of chemicals does Phenolphthalein identify?
Acids and bases.
