In Titration, to make sure we get a reliable and accurate result at first we will do a rough titration and we would do this by balancing the weigh boat to 0.00, use exact 2.5g of potassium carbonate, make sure the stopper your using is not broken and test it before using it. Look carefully at position of meniscus and it should be read from eye level. Raising the burette and glass pipette for every activity will help to reduce contamination, by doing these procedures we will get accurate results. After 25.9 cm make it drop by drop, to reduce the human error, there should be more than one person to do the experiment so they can get the timing right. Before using the conical flask, water it with distilled water
What else can I help you with?
What is the difference between rough and accurate titration?
Rough titration is an initial estimation to determine the approximate endpoint of a titration, while accurate titration involves fine adjustments to precisely determine the endpoint. Rough titration is typically done quickly and gives a ballpark figure, whereas accurate titration is more meticulous and provides a precise measurement.
How do you get accurate titration value?
To get an accurate titration value, ensure that all reagents are standardized and accurately measured, use an appropriate indicator, perform the titration slowly and carefully, and repeat the titration for consistency. Calibration and proper maintenance of equipment are also important for accuracy.
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 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 pilot titration?
Pilot titration is a preliminary test to determine the approximate endpoint of a titration process before conducting the actual titration. It helps in estimating the volume of titrant needed for the main titration, ensuring more accurate and efficient results. The data obtained from a pilot titration can help in planning and executing the main titration with greater precision.

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.
Why do we carryout blank titration in argentometric titration?
Blank titration is carried out in argentometric titration to account for any impurities or contaminants present in the reagents used. By measuring the volume of titrant required to reach the endpoint in the blank titration, this value can be subtracted from the volume used in the actual titration to determine the accurate amount of titrant required to react with the analyte.
Why is the indicator not added to the titration flask at the begging of the iodomettic titration?
Adding the indicator at the beginning of the iodometric titration can react with the iodine present, which can lead to errors in the titration results. By adding the indicator after most of the iodine has reacted, it ensures that the endpoint is more accurate and reliable.
What is the importance of blank titration?
Blank titration is important because it helps to account for any impurities in the reagents or solvents used in a titration experiment. By subtracting the blank titration values from the experimental titration values, more accurate results can be obtained. It ensures that the measured values are reflective of the actual reaction occurring between the analyte and titrant.
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.
How does the use of a burette make a titration precise?
A burette allows for precise and accurate measurement of the volume of titrant added during a titration. The graduations on the burette permit the volume to be read to high precision, enabling accurate determination of the endpoint of the titration. This facilitates precise calculation of the concentration of the analyte in the solution being titrated.
How do you achieve accurate volume of NaOH during titration?
To achieve accurate volume of NaOH during titration, you should use a calibrated burette to deliver the NaOH solution, ensure the meniscus of the liquid is at eye level when taking readings, and record the volume added precisely at the endpoint of the titration when the indicator changes color. Practice consistent technique and avoid parallax errors for accurate volume measurements.
