Why you do not use HNO3 or HCL in titration of redox?

HNO3 is not used in redox titration because being a good oxidising ageant it oxidises the compound itself whereas HCL is a very volatile and it takes part in the reaction therefore H2SO4 is used in the reaction


How do you use redox titration in lithium batteries?

Redox titration can be used to determine the lithium content in lithium batteries by titrating lithium ions with an oxidizing or reducing agent. This method helps ensure the accuracy of the lithium content in the batteries, which is critical for their performance. Redox titration is an analytical technique that allows for precise quantification of lithium ions present in the battery electrolyte or active materials.


What is the use of ferroin indicator in redox titration of Mohr's salt?

Ferroin indicator is used in the redox titration of Mohr's salt as it changes color when the Fe2+ ions are completely oxidized to Fe3+ ions. This color change helps in determining the end point of the titration, where all the Mohr's salt has been oxidized and no more Fe2+ ions are present.


How do you calculate the molarity of potassium iodate in redox titration?

To calculate the molarity of potassium iodate in a redox titration, you can use the balanced chemical equation for the reaction between potassium iodate and the reducing agent. By knowing the volume of the reducing agent used in the titration and the molarity of the reducing agent, you can determine the molarity of the potassium iodate. The equation should be balanced in terms of moles of the substances involved.


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.

What is the use of platinum electrode in potentiometry titration?

Platinum electrode is used as the indicator electrode in potentiometry titration to measure the potential difference between the indicator electrode and the reference electrode. It provides a stable and reproducible potential during the titration process, allowing for accurate determination of the equivalence point. Platinum electrodes are inert and do not participate in the redox reactions happening during the titration, making them suitable for a wide range of titrations.


What is iodometry and iodimetry titration?

Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.


Why use NaHCO3 for iodometric titration?

Sodium bicarbonate (NaHCO3) is used in iodometric titration as a reaction enhancer to neutralize excess acids that may interfere with the redox reaction between iodine and the analyte being titrated. By maintaining a slightly basic pH, NaHCO3 helps stabilize the iodine solution, ensuring more accurate and reliable results.


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


Why HCL is not use to acidify KMnO4 soln in permanganometric titration?

HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.


What is radiometric titration?

Radiometric titration is "regular" titration, but with the incorporation of a radioactive indicator to monitor the end-point. And that's right from the IUPAC Compendium of Chemical Terminology. If you need an example, use the link provided to a post on the radiometric titration of hexachloro-platinate (IV). It's a bit esoteric, but it will serve to exemplify the idea behind radiometric titration. It's pretty clear that when working with two precipitates (co-precipitation), the analyst would need a way to differentiate them. In the case cited, the application of radioactive cæsium-137 will permit the observer to more quickly and easily find a cutoff point at which to terminate the titration.


How do they use non-aqueous titration in pharmaceutical application?

"Titration" is the process of determining the concentration of one substance in another. When the titration is "non-aqueous", the substance which is being measured is present in a liquid other than water.
