Acid is added to the iron ammonium solution to lower the pH and prevent the hydrolysis of iron ions, which can affect the accuracy of the titration results. Acid also helps dissolve any precipitates that may form during the titration process, ensuring a clear and accurate endpoint.

Why was an acid added to the iron II ammonium solution before titration?

The acid is added to the iron II ammonium solution to prevent oxidation of iron II ions to iron III ions, which could lead to an inaccurate titration result. The acid helps maintain the iron II ions in their reduced state for the titration with the permanganate solution.


Which solution in the titration is taken in conical flask?

The solution being titrated is placed in the conical flask. The titrant (the solution being added during titration) is then slowly added to the solution in the conical flask until the endpoint is reached.


What is Over titration?

Over titration occurs when too much titrant is added during a titration process, leading to incorrect results. This can be due to human error, poor technique, or using an incorrect concentration of titrant. To avoid over titration, it is important to carefully monitor the reaction and follow the titration procedure accurately.


What is a titration-quenching?

Titration quenching is a process where a substance is added to a solution to stop a chemical reaction or change in pH during a titration experiment. This substance helps to stabilize the solution at the endpoint of the titration, ensuring accurate results.


What is titrant and analyte?

Titrant is the solution of known concentration that is added to the analyte during a titration to determine its concentration. The analyte is the substance being analyzed in the solution that reacts with the titrant.


Why is indicator added to a pipette solution before titration?

I'm not sure what you really mean. There wouldn't be any point adding it afterwards! It's there to reveal the end point of your titration. You could add it when you thought you were near the end point, but it's easier to put it in before you start.


Why is nitrobenzene added to titration mixture?

Nitrobenzene is added to the titration mixture as a color indicator for the endpoint of the titration. It imparts a pink color to the solution which disappears when the reaction is complete. This helps to visually determine when the equivalent point has been reached.


Why amnomiun thiocyanate is added in the titration of sodium thiosulphate with copper?

Ammonium thiocyanate is added in the titration of sodium thiosulphate with copper to detect the end point of the reaction. When all the thiosulfate ions react with copper ions, excess copper ions will react with ammonium thiocyanate forming a reddish-brown complex. This color change indicates that all the thiosulfate has reacted and the titration is complete.


What happens when ammonium chloride is added to water?

When ammonium chloride is added to water, it dissolves, creating ammonium ions (NH4+) and chloride ions (Cl-) in the solution. This dissociation process is endothermic, so it cools the solution. The resulting solution will be slightly acidic due to the presence of ammonium ions.


What difference between titration and back titration?

In fact, a back titration is carried out as in a very similar method to an ordinary titration. the only difference is in the context. Consider an unknown acid solution. Then a known amount of excess alkali was added to the solution and made them react. Then the process of finding the amount left from the alkali is known as the back titration.


What happens when a solution of sulphuric acid is added to a solution of ammonium hydroxide?

When a solution of sulfuric acid is added to a solution of ammonium hydroxide, a neutralization reaction occurs. The sulfuric acid will donate protons to the ammonium hydroxide, forming water and ammonium sulfate salt. Heat may also be produced in the process.


What is a solution of a known concentration used in the process of titration?

In titration, a solution of a known concentration is called the standard solution or titrant. It is used to react with the analyte solution of unknown concentration to determine the concentration of the analyte. The titrant is added to the analyte solution until the equivalence point is reached, signaling the end of the titration.
