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.
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
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.
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.

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

Why does Phenolphthalein turn pink in potassium hydroxide solution?
phenolphthalein is a weak acid, when reacting with strong alkali it turns pink
Why is ginger pink on Asian food but pale brown when it is a root?
If you slice raw ginger and place it in a white vinegar solution it will turn pink.
What solution does NOT turn cobalt chloride paper pink but boils at 100 degrees?
hydrochloric acid
What makes phenolphthalein turn alkali pink?
Phenolphthalein turns pink in the presence of a base or any solution with a ph over 7.
What would happen if there was no starch in the redox titration?
If you are looking at a iodide to iodine redox titration, the solution would turn yellow instead of blue/black. The blue/black color of the iodine-starch complex is very intense and so the end-point is sharper. Without the starch, the endpoint, when the first yellow from the formation of iodine I2, appears, is less sharp and is harder to see.
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.
