What is the difference between a redox indicator and an acid-base indicator?

Redox doesn't use indicators. It uses the natural colouration of the chemicals involved to determine the endpoint and titre. Acid-base titrations use a pH indicator, as otherwise there is often no way to tell the difference between an acidic solution and a basic one.

Difference between acid base titration and redox titration?
Acid base titration involves neutralization reaction between an acid and a base. whereas redox titration involves redox reaction between an oxidizing agent and reducing agent.
Why is an indicator not used in a redox titration?
Because the endpoints are easily observed.
What is the function of the phenanthroline solution that is added to the unknown iron solution?
phenanthroline is used as a redox indicator
What is redox titration?
Redox Titration refers to some titration based on the redox reaction between the titrant and analyte.
What is the function of starch solution in the redox titration?
It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)
Is starch redox indicator?
Starch is a complexometric indicator.
Difference between acid base titration and redox titration?
Acid base titration involves neutralization reaction between an acid and a base. whereas redox titration involves redox reaction between an oxidizing agent and reducing agent.
How does litmus in the litmus milk act as a redox indicator?
Litmus milk medium is skim milk to which the dye litmus has been added. Litmus is both a pH indicator and a redox indicator. It is pink at pH < 4.5, purple in middle pH's and blue at pH > 8.3. As a redox dye, in the absence of oxygen (reduced state) it's colorless (white due to milk) and in the presence of oxygen (oxidized state) it is purple.

What is redox mediator?
A redox mediator is a hyperbranched polymer having redox moieties (e.g. ferrocene) incorporated into its structure and/or chemically bonded to its periphery. It is attached to an electrode and assists in transferring electrons between the electrode and a redox enzyme.
Advantages and disadvantages using KMnO4 in redox titrimetry?
The advantage is that it acts as a self-indicator i.e. Does not need any indicator while the disadvantage is that it is a strong oxidizing agent therefore reacts vigorously and very fast.
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
What are the effects of safranin stain on the cell?
Safranin is a biological stain which generally colors the cell nuclei red. In analytical chemistry, it is also used as redox indicator.
