Why you use orthophosphoric acid in redox titration?
Orthophosphoric acid is commonly used as a buffer in redox titrations to maintain the pH of the solution. It also helps to prevent changes in pH that could interfere with the redox reaction being monitored. Additionally, it can complex with metal ions, helping to stabilize them in solution.
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.
Why do you care about redox?
Redox reactions are important in biological systems for energy production and metabolism. Understanding redox reactions helps us understand how cells generate and use energy to perform essential functions. Additionally, redox reactions are important in environmental processes such as the cycling of nutrients and pollutants in ecosystems.

Why is an indicator not used in a redox titration?
In a redox titration, an indicator is not used because the endpoint is determined by a change in the oxidation state of the analyte or titrant, rather than a change in pH or color. The endpoint is typically detected using a potentiometric method, such as a redox electrode, which directly measures the change in voltage.
Do pH levels effect electrons?
pH levels can affect the availability of free protons in a solution, which in turn can influence redox reactions that involve the transfer of electrons. Changes in pH can impact the balance of protons and electrons in a system, altering the overall electron transfer potential.
How do you constructing an eh-pH diagram?
Well, constructing an eh-pH diagram is like painting a beautiful landscape. You start by gathering data on the chemical species present in a system at different pH and Eh values, much like choosing your colors. Then, you carefully plot these points on a graph to create a visual representation of the system's stability, just like adding brushstrokes to bring your painting to life. With patience and attention to detail, you can create a masterpiece that helps you understand the behavior of your system.

Advantages and disadvantages of redox titration?
Advantages: Redox titration is versatile and can be used to analyze a wide range of substances, such as metal ions and organic compounds. It is also relatively simple and inexpensive compared to other types of titrations. Additionally, redox reactions typically produce clear and vivid color changes, making it easy to determine the endpoint. Disadvantages: Redox titrations can be sensitive to external factors such as pH, temperature, and presence of impurities, which can affect the accuracy and reliability of results. In addition, redox titrations may require more complex calculation methods due to the involvement of multiple oxidation states and stoichiometries.
What is the purpose of phosphoric acid in redox titration?
Phosphoric acid is used as a pH buffer in redox titrations to maintain a stable acidic environment, which is necessary for the reaction to proceed at a consistent rate. It also helps prevent the precipitation of metal hydroxides and ensures the correct formation of complexes that are vital for the titration process.
Difference between acid base titration and redox titration?
In acid-base titration, the reaction involves the transfer of protons between the acid and base, with the endpoint usually determined by a pH indicator. Redox titration, on the other hand, involves the transfer of electrons between the oxidizing and reducing agents, with the endpoint typically determined by a change in color or potential. Acid-base titrations are used to determine the concentration of acids or bases, while redox titrations are to determine the concentration of oxidizing or reducing agents.
