When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
Phenolphthalein is pink in a basic environment.
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.
Is there a reaction between the ammonium hydroxide inside a plastic bag when immersed in a water with phenolphthalein?
If the phenolphthalein solution turns pink, that means that the plastic bag is permeable to ammonium hydroxide. If it remains colorless, then the plastic bag is not permeable to ammonium hydroxide. If the contents of the plastic bag turn pink, then the plastic bag is permeable to phenolphthalein. If everything remains colorless, then the bag is impermeable to both ammonium hydroxide and phenolphthalein.
Is sodium hydroxide a base or acid how will you justify?
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
the colour changes to pink

What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
It Turns Pink.

Colors of sodium hydroxide in phenolphthalein?
pink to fuchsia or colorless depending on the amount of sodiumhydroxide . Sodium hydroxide is colorless. The Phenophtalein gives the solution its colour
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
the colour changes to pink
What does pink in phenolphthalein mean?
The solution is basic.
What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
At a particular point, the color of the indicator would change from colorless to pink (purple).
Why does the indicator goes purple in sodium hydroxide solution?
The most common one would be phenolphthalein which is colourless in acid and turns a pink-purple in base
What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions
What happens when you mix Sodium hydroxide and phenolphthalein?
it will turn pink. phenophathaline turns pink in alkaline ph
