Why does Phenolphthalein turn pink in potassium hydroxide solution?
phenolphthalein is a weak acid, when reacting with strong alkali it turns pink
What chemical reaction between the phenolphthalein and NaOH?
Phenolphthalein turns pink as NaOH is a strong alkali
What color does ammonia turn when phenolphthalein is added?
it turns into fushia/purpley colour
When a drop of phenolphthalein is introduced in lime water the solution turns?
When a drop of phenolphthalein is introduced in lime water the solution turns pink in colour.
Phenolphthalein solution is used as an indicator of acids and bases. If added to an ammonia-based solution of window cleaner we would expect the solution to turn?
As ammonia solution is alkaline, about pH 11 - 12, the phenolphthalein will turn pink.
Phenolphthalein goes what colour in a base?
Phenolphthalein turns pink in a base and turns colourless in a base
What is the colour of zinc ions mixed with ammonia in phenolphthalein indicator?
The phenolphthalein indicator is pink in basic solutions.

What happens when ammonia gas is passed through water containing phenolphthalein?
Ammonia gas get dissolved in water which form ammonium hydroxide. NH4OH is alkaline in nature. so when phenolphthalein is added to it. It produce PINK colouration.
When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
Phenolphthalein is pink in a basic environment.
What color does phenolphthalein change in bases?
For solutions with a pH higher than 8.2, phenolphthalein turns bright pink.
What is the indicator in titration reactions that turns pink in basic solutions?
phenolphthalein
