Why reaction mixture added into ice cold water before titration in experiment of kinetics of ester hydrolysis?
Adding the reaction mixture into ice-cold water helps to quench the reaction and halt any further ester hydrolysis. This is important to obtain an accurate measurement during titration, as it ensures that the reaction has stopped and the initial conditions are preserved for analysis. Rapid cooling also helps to minimize the impact of any side reactions that may occur due to heat generated during the process.

What sources of errors are there in a thermometric titration experiment?
Sources of errors in a thermometric titration experiment can include variations in room temperature, inaccurate temperature readings, improper calibration of the thermometer, variability in the reaction kinetics, and human error in accurately determining the endpoint of the titration.
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.
Why shaking of titration mixture is necessary?
Shaking of the titration mixture ensures thorough mixing of the reagents, leading to better reaction kinetics and more accurate results. It helps in achieving a homogeneous solution, enabling a consistent reaction rate throughout the sample. Additionally, shaking also aids in improving the precision and reproducibility of the titration.
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.
Is sucrose a hydrolysis reaction or a condensation reaction?
Sucrose hydrolysis is a type of reaction where water is used to break down sucrose into its constituent monosaccharides, glucose, and fructose. It involves the addition of water to break a chemical bond. Thus, sucrose hydrolysis is a hydrolysis reaction.
