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
Is sodium hydroxide a homogeneous mixture?
No, sodium hydroxide is a pure substance.
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.
Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
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.
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
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.

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 colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
Sodium Chloride is neutral. And Phenolphthalein is colourless when neutral.
What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions

Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
It Turns Pink.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
Pink
