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.

Is starch redox indicator?
Starch is a complexometric indicator.
Is browning banana a redox reaction?
A browning banana is a redox reaction.
How can a galvanic cell become an electrolytic?
the redox reaction is reserved
What substance is needed to reverse a biochemical reaction?
Redox is what is needed to reverse a biochemical reaction. The redox is used in science.
A single-displacement reaction and a double-displacement reaction are always redox reactions.?
Single displacement reaction and a double displacement reaction are redox reactions. apex- false
Why is no indicator needed in redox titration experiment?
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.
How can you tell for sure that a redox reaction has happened?
if oxidation states change, it is a redox reaction
Why are there blue precipitate at the end of redox titration?
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.
What is the theory of the redox titration?
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.
Is starch redox indicator?
Starch is a complexometric indicator.
Is browning banana a redox reaction?
A browning banana is a redox reaction.
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.
How can one identify a redox reaction?
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.
