Why don't we use indicators in redox-titration?
Because the end point can easily be observed. Example: consider the titration between potassium manganate (IV) which is purple and ammonium iron (II) sulfate - colourless. At the end point the colourless standard solution will turn pale pink when the correct volume of deep purple titre is added. No indicator is required. Also this is not necessarily an acid base rxn
What happens if ethene is shaken with bromine water?
The solution will turn the orange bromine water into a colourless solution
Why did the solution turn to pink at the of the titration?
because the solution react with sulphuric acid. other than that, the end point is indicated.
Why did the solution turn to pink at the end of the titration?
because the solution react with sulphuric acid. other than that, the end point is indicated.
How does white dextrose powder turn a blue color while adding water?
It doesn't. The solution produced is colourless.
What is the colour of phenolphthalein in salt water?
It will turn purple
How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.

Why did the solution turn into light pink at the end of the titration?
The pH was changed.

Will the carbon dioxide turn colourless solution when the carbon dioxide is passed continuously into limewater?
yes it will.... anyone know why ??? :) no

It doesn't. The solution produced is colourless.
Why is important that the indicator is present in the solution during the course of titration?
the reason why a indicator is important in some titration is to show a change in the solution. for example as a solution runs from acidic to basic the indicator may turn a different color. but this is the reason why it is important inmost experiments.
How do you determine the end point from titration in acid base titration process?
it depends on the indicator used, i.e. phenolphthalein is the most popular. this is colourless in acid, purple in base, very identifiable. Keep actively swirling and when it is expected to turn (figured from a rough titration beforehand) add very slowly dropwise untill the colour turns.
What is the test for unsaturation?
Add KMnO4 (Potassium Permanganate) which is a purple solution. If it is added to an alkene or alkyne it will turn colourless and produces a brown precipitate.
