Which reaction take place during titration?
During a titration, a chemical reaction occurs between the analyte (substance being analyzed) and the titrant (solution of known concentration). The reaction typically involves an acid-base reaction, redox reaction, or precipitation reaction, depending on the purpose of the titration and the substances involved. The endpoint of the titration, when the reaction is complete, is indicated by a color change, pH change, or other measurable change.
Why the titration flask need to be shake during titration?
Shaking the titration flask during titration helps to ensure that the reaction mixture is well-mixed and that the titrant is evenly distributed throughout the solution. This promotes a more uniform reaction and more accurate measurement of the endpoint of the titration.
Why the titration cannot get the accurate result?
Titration may not give accurate results due to factors such as improper calibration of equipment, presence of impurities in the sample, incorrect reading of the endpoint, or incomplete reaction during titration. It is important to carefully follow the experimental procedure and ensure all equipment is working properly to obtain accurate results.
What is a titrand in titration analysis?
A titrand is the substance in a chemical reaction that is analyzed or measured during a titration. It is the substance that undergoes a change in its chemical properties due to the addition of a titrant during the titration process.
Why stir during titration test?
Stirring during titration helps to ensure that the reactants are thoroughly mixed, resulting in a more accurate and uniform reaction. This helps in achieving a sharp endpoint and accurate results in the titration test.

What is titration error?
Titration error is simply the difference between the end point of a titration and the equivalence point of it. It can mathematically defined as Error = Vol(End Point) - Vol(Equivalence Point)
Why there is a need to warm the solution of sulfuric acid and oxalic acid during redox titration?
Warming the solution of sulfuric acid and oxalic acid during redox titration increases the reaction rate, making the titration process faster and more efficient. The elevated temperature helps to ensure that the reaction between the two compounds proceeds to completion, resulting in more accurate and reliable titration results.
Why need to add reagent drop by drop during titration?
Adding reagent drop by drop during titration allows for precise control of the reaction and helps prevent over-titration. This ensures that the endpoint is accurately determined and the titration results are as precise and reliable as possible.
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 purpose of hydrochloric acid in iodine titration?
Hydrochloric acid is used in iodine titration to acidify the solution, which helps in the release of iodine gas from the reaction between iodide and iodine. This ensures that the reaction reaches completion and that accurate results are obtained during the titration process.
How temperature affects titration experiments?
Temperature can affect titration experiments by influencing the rate of reaction. Higher temperatures can increase the rate of reaction, leading to faster titration results. Additionally, temperature can impact the solubility of the reactants, potentially affecting the concentration and accuracy of the titration. It is important to control and monitor the temperature during titration experiments to ensure reproducibility and accuracy of the results.
Why you add starch at the end of titration?
Starch is added at the end of titration as an indicator to signal the endpoint of the reaction. It forms a complex with the iodine produced during the titration, resulting in a color change from clear to blue-black, indicating that the titration is complete.
