Is iodometric titration and redox titration is same?
No, they are not the same, but 1 is part of 2.Iodometric titration is just one of the (larger) group (or class) of oxidimetric titrations, which in turn is part of the much (larger) group (or class) of volumetric analysis method.
Why the solution turn to pink at the end of thr titration?
The solution turns pink at the end of the titration when an indicator like phenolphthalein is used to detect the endpoint. In this case, phenolphthalein turns pink in basic solutions, indicating that the acid has been neutralized and the endpoint of the titration has been reached.
Why did the solution turn to pink at the end of the titration?
The pink color at the end of the titration could be due to the indicator phenolphthalein, which turns pink in basic solutions. This indicates that the solution has reached its endpoint and is slightly basic.
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 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.
Why did the solution turn into light pink at the end of the titration?
The pH was changed.

Why do clouds turn purple and pink at sunset?
The clouds turn pink and purplish at sunset because the light becomes polarized.
Why does a pink object turn purple when there is a blue light on it?
When you mix pink/red and blue, you get purple.
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.
What color will a solution be at the equivalence point of titration?
The color of a solution at the equivalence point of a titration depends on the type of indicator used. The indicator changes color at a specific pH value, signaling the completion of the reaction. Common indicators like phenolphthalein turn pink at the equivalence point of an acid-base titration.
Why did the solution turn to pink at the end point of the titration?
The pink color indicates that the pH has reached a specified endpoint in the titration process. In acid-base titrations, a pink color is often associated with the addition of an indicator such as phenolphthalein which changes color at a specific pH, typically around pH 8.2-10. This color change signals the completion of the reaction between the acid and base being titrated.
