An example of a redox reaction that does not require an indicator is the reaction between zinc metal and hydrochloric acid to produce zinc chloride and hydrogen gas. This reaction can be observed directly by the effervescence of hydrogen gas being evolved without the need for an indicator to detect the change in oxidation states.

Redox is what is needed to reverse a biochemical reaction. The redox is used in science.
Single displacement reaction and a double displacement reaction are redox reactions. apex- false
No indicator is needed in redox titration because the endpoint of the titration is determined by a change in the appearance of the titrand. This change can be detected visually, such as a color change, indicating the completion of the reaction without the need for an indicator.
if oxidation states change, it is a redox reaction
The blue precipitate may indicate the presence of excess indicator in the solution. In redox titrations, the indicator changes color when the reaction reaches its endpoint. If too much indicator is added, it can form a colored precipitate due to its reaction with the titrant, which can obscure the endpoint of the titration. It is important to carefully control the amount of indicator to avoid this issue.
Redox titration is a type of titration based on a redox reaction between the analyte and titrant. The theory behind redox titration is that the number of electrons transferred in the reaction is used to determine the amount of substance being analyzed. This is typically done by monitoring the change in concentration of a redox indicator or analyzing the endpoint using a potentiometric method.
Starch is a complexometric indicator.
A browning banana is a redox reaction.
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.
A redox reaction can be identified by the transfer of electrons between reactants. Look for changes in oxidation states of elements involved in the reaction to determine if it is a redox reaction.
