Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
What happens when you mix calcium hydroxide and phenolphthalein?
It changes colors
What happens when you mix Sodium hydroxide and phenolphthalein?
it will turn pink. phenophathaline turns pink in alkaline ph
Is adding phenolphthalein to sodium hydroxide a chemical change?
The actual process of adding it is not. However, a chemical change does occur immediately after the addition.
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 is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is the indicator to see if it is more acidic or more basic
What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions
What is the action of sodium hydroxide on the colour of phenolphthalein?
Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
It Turns Pink.
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.
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein, because NaOH is a strong base.
What happens when you mix Sodium hydroxide and phenolphthalein?
it will turn pink. phenophathaline turns pink in alkaline ph
Is adding phenolphthalein to sodium hydroxide a chemical change?
The actual process of adding it is not. However, a chemical change does occur immediately after the addition.
Why does sodium hydroxide and phenolphthalein mixture turn clear when carbon dioxide is added?
Carbon dioxide dissolves in the aqueous solution to produce carbonic acid. The carbonic acid dissociates to produce the carbonate ion and two protons. The protons reacts with the hydroxide provided by the already dissociated sodium hydroxide to produce water. The sodium carbonate is fairly soluble and stays in solution. Since the hydroxide ion is depleted, the phenolphthalein reverts from pink to clear as it does in solutions with a pH less than 8.3.
