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
When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
Phenolphthalein is pink in a basic environment.
Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
What is the colour of the precipitate formed when a calcium salt reacts with sodium hydroxide solution?
A white hydroxide: Ca(OH)2.
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.

What happens when you mix calcium hydroxide and phenolphthalein?
It changes colors
When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
Phenolphthalein is pink in a basic environment.
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.
Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
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
What is the colour of calcium hydroxide?
White as pure, dry substance
What does quicklime and water make?
A vigorous reaction between water(steam) and quicklime produces calcium hydroxide as a residue.
What is the colour of the precipitate formed when a calcium salt reacts with sodium hydroxide solution?
A white hydroxide: Ca(OH)2.

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 the indicator to see if it is more acidic or more basic
